This paper investigates the effects of cover ratio and soil strength parameters (cohesion and
friction angle) on the failure mechanisms of cohesive soils overlying trench voids using …

This paper focuses on the stability analysis of three-dimensional rectangular trapdoors
beneath cohesive-frictional soils via three-dimensional finite element limit analysis (3D …

Even though extensive research works have been carried out to understand the trapdoor
responses in frictional materials, those in cohesive–frictional materials have not yet been …

abstract To study the mechanical behavior of crushed rock aggregate, a series of large-scale
direct shear tests were conducted. Then the particle flow model was established with PFC3D …

In terms of its geological description, dissolution of the ceilings of the karst pits, and large
and deep pits formed by karstic dissolution are defined as a sinkhole. Sinkholes, as they …
