Soft clays are highly compressible, high-water content, low shear strength, and have poor permeability, which result in significant settlement under long-term loads. Therefore, one of the most challenging geotechnical engineering problems is to predict from soft clay soil. Normalized Rotational Multiple Yield Surface Framework (NRMYSF) developed soil stress-strain behaviour strength characteris...

Earth pressure coefficient at rest K0 is commonly estimated by empirical equations, which to date has had insufficient accuracy and universality. For better prediction, the investigation on factors influencing required. A series of discrete element method (DEM) simulations oedometer tests are conducted verify key granular materials. The influences initial fabric anisotropy, particle shape, void...

The paper investigates strike-slip fault rupture propagation through dense sand and its interaction with surface foundations, employing 3D finite element (FE) modelling. Two soil constitutive models (implemented in Abaqus user subroutines) are employed for this purpose: (i) a recently developed simple yet efficient model Mohr–Coulomb yield criterion, which incorporates post-yield isotropic fric...

Temperature significantly affects the mechanical properties of geomaterials, particularly creep behavior soft clayey soils. Thus, an appropriate constitutive model to describe time-dependent stress-strain soils at various temperatures is necessary. This study performed temperature-controlled oedometer tests on two soils: Hong Kong marine deposit (HKMD) and kaolinite clay (kaolin). The thermally...

A bounding surface plasticity model based on the effective stress concept is presented to describe behaviour of unsaturated structured soils subjected hydro-mechanical loadings. The structural degradation effects compressive and tensile strength are considered through controlling size surface, allowing for a smooth transition response from unstructured states. modelled using work hardening appr...

expansive soils show swelling and shrinkage behavior when subjected to cyclic wetting and drying. the variation in water content influence the volume change in this kind of soil. these volume changes can cause ground movement which may result in damage to the buildings and structures. to study the behavior, a number of successive wetting-drying cycles were conducted on a statically compacted ex...
