Cyclic loading always results in great damage to the pore structure and fractal characteristics of soft soil. Scanning electron microscope (SEM) can help collect data describe microstructure This paper conducted a series SEM tests interpret effect consolidation confining pressure, circulating dynamic stress ratios overconsolidation ratio on soil’s micro-pore characteristics. The demonstrate tha...

Clastic soil is ubiquitous in practice but still poses a challenge for testing and modelling. Conventional laboratory tests with small sizes are not suitable the large grain size, while large-scale field often too costly time-consuming. In this paper, mechanical behaviour of clastic described by hypoplastic constitutive model based on numerical simulations considering both matrix breccia. The i...

In practical engineering projects, overconsolidation plays an irreplaceable role in the calculation of silt consolidation settlement. Based on a series systematic tests conducted reconstituted soft clay different cities Guangdong-Hong Kong-Macao Greater Bay Area, behavior under depths was studied. According to these tests, shape curves ratio with depth similar that compression curves. Moreover,...

The undrained shear strength of clay is an important index for the calculation bearing capacity foundation soil, soil pressure pit, and analysis slope stability. Therefore, purpose this paper to conduct a comprehensive study combined use machine learning with theoretical equations estimate it. Under Bayesian framework, CatBoost algorithm (CatBoost–Bayesian) based on optimization was developed o...

This paper regards soft rock as a heavily overconsolidated clay and proposes new fractional elastoplastic model to describe its temperature-dependent mechanical behaviour. Together with the critical state mechanics, subloading surface concept is adopted capture irreversible plastic deformation developed inside normal yield provides smooth transition between elastic zones. In addition, proposed ...
