The propagation and coalescence of discontinuous cross-type joints are often the primary drivers of rock slope failures. Due to the inherent randomness of these joints, identifying suitable methods to accurately characterize progressive failure and q

Understanding the cracking process of layered tunnels requires a high-fidelity method. Improved smooth particle hydrodynamics (SPH), termed kernel broken SPH (KBSPH), was implemented to simulate the crack propagation and deformation of layered rock c

A time-scale varying finite difference method (TSFDM) was proposed to analyze the influence of rainfall infiltration and water level fluctuation on the stability of a bank slope in the Yunnan Pulang tailings pond. The stability of the slope obtained

The strength and hydraulic conductivity anisotropy of rock slopes have a great impact on the slope stability. This study took a layered rock slope in Pulang, Southwestern China as a case study. The strength conversion equations of the seriously weath

In the study of the seepage characteristics of layered rock slope under rainfall conditions, the majority of previous research has considered the hydraulic conduction to be isotropic, or only considered the anisotropy ratio of the hydraulic conductiv

Breaching of a dam depends on the complex interaction between the dam and the backwater lake. Here, we conduct a series of experiments to investigate the failure mechanisms of landslide dams by considering debris composition and geomorphic parameters
