Effect of pore air escape and cement dissolution on granite residual soil disintegration, southeast China [PDF]

Scientific Reports
Granite residual soil in south and southeast China has obvious characteristic of disintegration, which induces collapse erosion and shallow landslide. Although the escape of pore air can be observed in the present hydrostatic water tests, and pore air ...

Characteristics of wetting behavior under unloading in natural granite residual soil. [PDF]

Sci Rep
Abstract Excavation of foundation pits induces stress release in the soil, leading to deformation driven by the redistribution of internal stresses and particle adjustment. Rainfall infiltration further increases soil water content, weakening particle bonding through the dissolution of cementing agents, and inducing additional wetting ...
