摘要:The aim of this paper is to determine the critical supporting pressure on the circular face of an advancing tunnel in undrained clay in which undrained strength increases linearly with depth. Based on the kinematic approach of limit analysis, a continuous velocity field with a to...

摘要:Stiffness at very small strains G 0 is commonly assessed by way of laboratory and field methods, and used to design a wide range of infrastructure. When stiffness is inferred from field measurements, its value depends on the soil suction and state of saturation at the time o...

摘要:Punch-through failure of mobile jack-up rigs is still a main concern for spudcan foundations. Using centrifuge model tests and numerical modelling, this paper examines the mitigating effect of top-mounted sleeves and a downward skirt on spudcan punch-through in medium dense sand ...

摘要:Bearing capacity of shallow foundations is higher following preload (or self-weight)-induced consolidation because the soil strength changes, and perhaps because the failure mechanism changes. Previous studies have illustrated this effect by plotting or predicting changes in eith...

摘要:Clay-rich rocks are potential geological barriers for geological repositories of radioactive waste. The long-term safety of a repository requires a full characterisation of the time-dependent thermal hydro-mechanical behaviour of the clay-rich rocks. This paper investigates the c...

摘要:Water uptake intensity (WUI), which depicts the relationship between the rate of plant root water uptake per unit soil volume and soil matric suction, has been commonly used to analyse the transpiration-induced soil hydrological changes in civil infrastructure. However, the effec...

摘要:The design of piles subjected to tensile loading is usually done by applying a correction factor on the shaft resistance calculated for compressive loading, but experimental data on what this correction factor should be are limited. This paper presents the results of a serie...

摘要:An investigation into using Portland cement (PC)-based and magnesia (MgO)-based binders for treating contaminated model soil was carried out to study the benefit of novel binders over conventional ones in stabilisation/solidification systems (S/S), as well as the binding mechanis...
