Construction projects are subject to numerous risks that could have consequences on project success. Therefore, it is necessary to manage project risks by modelling them. Risk Breakdown Structure (RBS) is a hierarchical formalisation method of risks facilitating their identification and analysis. Project risks have a dynamic nature; they evolve thr...

Mining can be the source and target of opportunities and threats of different natures exceeding the mine site perimeter, affecting the socio-ecological system and leading to social conflicts and entrepreneurial risks for mining companies. Hence, a mining project is a matter of land planning rather than a simple industrial object. Nevertheless, curr...

Flood management is particularly important for many urban territories. In order to assess the interest of different risk mitigation strategies, it is necessary to consider the human behavior. Different models and approaches are available to model and simulate people behaviors during a flood event. Despite the considerable recent progress of these m...
Article
Full-text available
Underground voids caused by tunneling or mining activity produce soil movements and may expose structures to physical and/or functional damage. To assess structures vulnerability, soil-structure interaction (SSI) parameters are modeled using probability distribution laws to consider their complexity and their uncertainty. Therefore, the target of t...

The objective of this paper is to investigate the influence of various geometrical uncertainties of analytical modelling affecting the evaluation of building deflections induced by tunnelling or mining subsidence. Based on Winkler model coupled with an elastic Euler-Bernoulli beam, an analytical approach is applied to evaluate the influence of majo...
Article
Full-text available
Les risques et les opportunités liés à l’activité extractive dépassent largement le périmètre des sites miniers eux-mêmes. De ce fait, les projets miniers doivent être considérés comme des enjeux d’aménagement et de développement potentiel du territoire plutôt que comme de simples objets industriels isolés. À titre d’exemple, en Guyane, l’exploitat...
Article
Mining is the source and target of various risks, that generally exceed the mine-site perimeter, and have impacts at larger scales. Consequently, mining risk analysis should be informed both by the structured characterization of mining projects and by a holistic understanding of the system where mining projects are located and interact. This is rar...
Article
An efficient probabilistic approach is presented to consider the uncertainty related to the evaluation of the transmission of ground movements to structures considering the influence of the variability of the soil-structure interaction (SSI) parameters (namely the building stiffness EI/B, the soil modulus k and the structure length L). These moveme...
Article
Full-text available
In order to determine the bearing capacity of shallow foundations, most of the analytical methods take the assumption that the soil layers below the foundation are homogenous, horizontal and are extended to a great depth. However, in reality, the geological structure under the foundation is much more complex and far from simplifying the taken hypot...
Article
Many buildings may suffer damage due to ground movements associated to underground excavations like tunneling, mines or urban excavations. The level of damage depends upon the rate of ground movements transmitted to structures that is affected by the soil-structure interaction (SSI) conditions and parameters such as the soil elastoplastic behavior....

Whenever a flood happens, emergency services must deal with inhabitants that may agree or disagree the recommendations to evacuate. This paper investigates a model that aims to assess the number of unevacuated inhabitants in tall buildings located in urban areas when a flood occurs, considering different uncertainties that make the prediction diffi...
Conference Paper
Full-text available
Despite its contribution to economic development, mining may be the source and target of risks of different nature and the origin of social conflicts at the territory level. However, the uniqueness of mining activities and their inherently interdisciplinary character are often not taken into consideration in risk analysis. As a matter of fact, risk...

In the last 20 years, more than 40 major tailing dam accidents occurred posing major economic, social and environmental threats like for instance, the dam failures of Baia Mare in Romania (2000), Mariana in Brazil (2015) and again in Brazil with the recent Brumadinho dam failure (2019). There are several existing methods to monitor the safety and e...

Many buildings may suffer damage due to ground movements associated to underground excavations like tunnelling, mines or urban excavations. Assessment of the transmitted ground movement is then one of the major concerns and soil plasticity may have a significant influence on structural behaviour due to the Soil-Structure Interaction (SSI). The purp...
Conference Paper
Full-text available
Sources of ground movements, like tunneling, shrink-swell phenomenon of clay soils, mining subsidence, etc., may create a significant soil settlement. This can have an important impact on nearby buildings due to the deformation caused by the variation of the soil level. To simplify, design engineers may consider that the building totally follows th...

Physical and mechanical properties of soils have spatial heterogeneities whose origins come from the complexity of the involved natural geological processes that lead to their constitution. This spatial heterogeneity is associated with an uncertainty on each of the parameters usually used to quantify the natural variability that represents the soil...

Mining activities in tropical regions might be the source and the target of multiple risks. The peculiar climatic conditions are the main reasons of their complexity and their interactions with the human and natural environment need to be considered carefully. Risk factors vary according to internal and external conditions of mining projects and ca...

The infrastructures of modern society are connected in a complex network, relying on each other for their own functionality. When one or more infrastructure fails, it can also cause other dependent infrastructures to fail or suffer from reduced efficiency, which can lead to problems with further infrastructures in a cascade effect. By finding the m...

ABSTRACT. Due to the heterogeneity of soils and the complexity of the studied phenomena, the geotechnical engineer has to cope with random and epistemic uncertainties which restrict the prediction of soil’s mechanical behaviour. In order to obtain more reliable results when there is a lack of field data, it therefore seems relevant to take into acc...

Structural collapse is the ultimate and most spectacular manifestation of construction project failure. More generally, the project objectives are not only structural stability and safety, but the fulfillment of cost, delays and performances. The authors have developed a systemic approach of construction projects in which risk events are highlighte...
Article
A significant number of construction failures and collapses occur during the construction phase, and in most of the cases, these failures involve the temporary structures. An important reason of such accidents, which often is neglected, is disregarding the temporary structures in project risk management process. For this very important reason, we h...

Mining can be the source and target of opportunities and threats of different natures exceeding the mine-site perimeter, affecting the socio-ecological system where mining is performed and leading to social tensions and entrepreneurial risks for mining companies. Hence, a mining project is a matter of land-planning rather than a simple industrial object. Nevertheless, current mandatory risk and impact assessment methods are often performed on one project at a time, sometimes neglecting the cumulative dimension of risks, the great variability of coexistent mining activities, and the socio-ecological vulnerability in which mining is performed. This thesis proposes an approach to develop and compare, based on the assessment of their risk, different potential scenarios for land-planning strategies in mining territories. This approach is operationalized through the development of a framework via its application on French Guiana gold mining sector. Here, gold mining involves a great variety of forms and techniques in a very sensitive socio-ecological context.
Project
Le projet RGC4 - porté par l’Ecole des Ingénieurs de la Ville de Paris - ambitionne le développement d’outils opérationnels pour l’amélioration de la continuité d’activité des services urbains et des réseaux techniques associés face aux inondations. Concentrées sur le territoire du Grand Paris, nos recherches se focalisent sur des scénarios de crues importantes de la Seine caractérisées par une cinétique lente. Le projet prévoit d’abord une analyse comparative des retours d’expérience de villes ayant affronté ce type de phénomène, ainsi que des outils déjà existants pour la modélisation des risques de défaillance en cascade des réseaux soumis à aléas.
