... under-explored. This study integrates a bounding surface modified Cam-Clay model with the sliding–consolidation framework to simulate landslide kinematics under seasonally fluctuating water tables. The results categorise four regimes of landslide motion based on stress state: healing, neutral, stable...

Based on the laboratory data, the normalised yield stress for cyclic loading (NYCL) is introduced as an insightful parameter to define a novel empirical relationship between the yield stress...

... balance equation can be recovered by considering a consolidation process confined within the liquefied layer and regulated only by vertical fluid flow, as follows: 2 k γ w ∂ 2 p w ∂ z 2 + ε ˙ = 0 where z indicates the direction...

...Ci Wang; Conleth D. O'Loughlin; Fraser Bransby; Phil Watson; Zefeng Zhou Motivation for this paper stems from experimental investigations that consider how the vertical capacity of a horizontal circular plate anchor in clay changes due to consolidation. These experiments produced interesting time...

...Xiuli Sun; Ruoxuan Zheng; Yu Wang; Xun Jin; Qinjie Yu Energy consumption has emerged as a hot topic and cutting-edge research theme in the application of electro-osmotic consolidation of low-permeability soils. However, the resistance of circuits in an electro-osmotic consolidation system...

...Hao Zhang; Yu-Jun Cui; Hong-Lei Sun; Yuan-Qiang Cai The widespread utilisation of vacuum-assisted prefabricated vertical drains for managing clayey soft ground has led to the development of numerous consolidation models. However, these models have limitations when describing the filtration...

... geotechnical processes. To demonstrate feasibility, in this study a physics-informed data-driven approach is developed to automatically recover Terzaghi's consolidation theory from measured data and obtain the corresponding solutions. This process incorporates several algorithms including sparse regression...

...Linzhong Li; Aifang Qin; Lei Wang; Lianghua Jiang The feasibility of Carrillo's method is confirmed for consolidation problems of unsaturated soils under instantaneous loading in this study. In the plane strain and axial symmetry consolidation models, the coupled governing equations expressed...

.... The internal wall of the strong box was greased to minimise friction between the consolidating clay and the container. The piston load was then reduced gradually from 800 kPa to 80 kPa, taking care to avoid cavitation by ensuring that the negative excess pore pressure never exceeded 100 kPa. Fig. 3...

Although viscosity is not necessary to carry out propagation analyses, ignoring it leads to unrealistic estimates of peak velocity and runout distance. As a result...

In order to hasten consolidation, prefabricated vertical drains (PVDs) were installed beneath the entire footprint of the embankment in a square 1·2 m grid, with each drain installed through the 0·4 m thick sand drainage layer and into sandy...
