Soft soil suffered from different aspects for example high compressibility and low shear strength; in which cannot provide satisfactory support to any structure. In order to support such type of soil, the synthetic/natural fiber reinforcement has been recently suggested to ensure the stability of buildings and infrastructures. This technique involv...

Abstract. The aim of this research is to investigate the behavior of unpaved roads using a 3D finite element model using a well-known commercially available finite element package ‘ABAQUS’ version (6.12-1). The reinforcement geogrid spread the traffic loading on a wider area and effectively transmitted the pressure to the underlying foundation s...

Abstract:The addition of waste plastic bottle strips to soil as a reinforcing material is widely used nowadays to enhance the engineering properties of soils. In this study, series of unconfined compression tests were conducted on clayey sand soil with and without adding strips of waste plastic bottle to investigate the effect of adding plastic str...

Tunneling may cause serious damage to the existing structures. This is because the tunneling is an unloading process which can change the stress along the existing pile. Therefore, studying the influence of tunneling on the existing pile foundation is important. This study uses an experimental model to evaluate the influence of the tunneling on the...

This research is concerned with the use of petroleum residues to stabilize Baiji sand dunes. The purpose of this research is to study the stabilizing effect of these residues irrespective of their possible toxicity to plant and environment. Two petroleum mixtures were prepared in different mulching rates to test their efficiency in stabilizing sand...
Article

Shell foundation has been considered as the best shallow foundation for transferring heavy load to weak soils because of the high bearing capacity values, where a conventional shallow foundation submit to excessive settlement. An experimental work has been conducted to investigate the behavior of pyramidal shell foundations as compared with flat co...

Tunnel construction below or adjacent to piles will affect the performance and eventually the stability of piles due to ground deformation resulting in the movement of piles and changes in the axial force distribution along the piles. A three dimensional finite element analysis using PLAXIS 3D (2013) was performed to study the behaviour of a single...

A combination of axial and lateral was applied on a small scale model piles embedded in layered sand soil. Two types of piles were used (open and closed ended steel box piles), while the relative density (D r) of the upper and lower sand layers were (55%) and (85%) respectively. The effect of slenderness ratio (L/D) were also considered in this stu...

The characteristics of organic soil are low permeability, low shear strength and high compressibility, therefore organic soil has to be improved before any engineering works can commence. In this study dry kaolinite is used as a clay minerals and fresh reed as an organic material for different percentages (0%, 2%, 5%, 8%, 12% and 20%) by dry weight...

This study is concerned with investigating the advantages of using prefabricated vertical drains (PVD) to improve the foundation soft soil under an embankment. PVD combined with staged construction of embankment is considered as a common technique to reduce both the time for full consolidation and the excess pore water pressure. Rocscience Settle 3...
Article
A series of 25 laboratory model tests was conducted to investigate the feasibility of using a granular trench reinforced randomly with Geogrid Micro Mesh (GMM) to achieve further soil improvement in terms of bearing capacity ratio and settlement reduction percentage as compared to the same trench systematically reinforced with layers of geogrid. Th...

This paper is devoted to make use of the boundary element method as a practical problem solving tool to analyze the soilpile interaction problems. A computer program was adopted for the analysis process. It is a computer package called PGroupN which is concerned mainly with the analysis of the pile group problems. A non-linear soil model has been a...

Grouting technique has been widely used during the recent decades to overcome construction problems in difficult soils. Scientific recommendations to use such technique should be based on standard experimental testing not on guess. So, a grouting apparatus is manufactured according to ASTM D4320-84 to evaluate strength characteristics of sand soil...

The boundary element technique is a practical problem-solving tool and useful in comparison to other currently popular alternatives. In this paper, a circular tunnel with a diameter of 3.4 m is to be excavated through a clayey soil and surrounded by concrete lining of a thickness 0.2 m, so the clear internal diameter is 3.0 m. A plane strain analys...

This paper is an attempt to solve the soil-pile interaction problems using the boundary element method (BEM). A computer package called PGroupN, which deals mainly with the analysis of the pile group problem, is employed in this study. Parametric studies are carried out to assess the impacts of the pile diameter, pile length, ratio of spacing to di...

The boundary element method (BEM) has become one of the most powerful numerical techniques which has already established itself within the scientific community. The most striking feature of this technique is that, in principle, only the boundaries of the region being investigated have to be discretized, which therefore leads to many fewer discrete...
