Article
Jacking forces which exceed expectations constitute a risk for tunnelling contractors. One scenario in which high forces may arise is when jacking of lubricated pipes is temporarily halted, which was considered by Li et al. using a programme of direct shear testing. While recognising the importance of the topic to the profession, the purpose of thi...
Article
Deep large-diameter caisson shafts are a popular means of constructing underground storage and attenuation tanks and pumping stations for the water and wastewater industry. One of the key design concerns for these structures is resistance to flotation during periods where the tanks are only partially filled or empty. This paper uses two-dimensional...
Article
An accurate estimation of the jacking forces likely to be experienced during microtunnelling is a key design concern for the design of pipe segments, the location of intermediate jacking stations and the efficacy of the pipe jacking project itself. This paper presents a Bayesian updating approach for the prediction of jacking forces during microtun...
Article
Open caisson shafts are a widely adopted solution for a range of geotechnical applications. An external ‘cutting shoe’ is a common construction feature used to reduce the soil frictional resistance acting on the caisson during sinking. This forms an annular void encircling the caisson which is filled with a support fluid to maintain excavation stab...

An open-dug caisson shaft is a form of top-down construction in which a concrete shaft is sunk into the ground using the weight of the shaft and additional kentledge, if required. Excavation at the base of the caisson shaft wall allows the structure to descend through the ground. A thorough understanding of the interaction between the caisson shaft...

The primary objective of this research is to develop intelligent, automated methods for instrumenting, measuring and monitoring SSI, to provide real-time feedback to site engineers and to develop current design methods. New contact stress transducers will be developed using optical sensing technology, alleviating the limitations of current transducers. The monitoring systems will be deployed on upcoming candidate construction projects with our industry partners.
