New scientific issues in the study of high-elevation and long-runout landslide dynamics in the Qinghai-Tibet Plateau by GAO Haoyuan, GAO Yang, YIN Yueping, ZHANG Tiantian, WAN Jiawei

“…The dynamic mechanism of high-elevation and long-runout landslides is always a tricky problem in geological disaster research. Due to the complex geological conditions in the Qinghai-Tibet Plateau, high-elevation and long-runout landslides show more complex and robust dynamic action, resulting in disaster chains of ultra-high elevation and ultra-long distance. …”

Failure experiment of soft-hard interlayer bedding rock slope by Mingjian Tan, Chunmei Zhou, Dong Sun, Zichao Zhou

“…In view of the prone and frequent occurrence of such slope geological disasters, research is carried out from the aspects of slope angle, rock formation tendency and combination form, and joint distribution.Slope physical model testing is an important means to reveal the mechanism of slope deformation and failure.Based on similarity theory, this paper takes the Sunjia landslide in Wanzhou District, Chongqing City, as the engineering support and designs the indoor slope physical model test according to the geological exploration report of the landslide area.The test simulates gravity loading through a jack-up model box and explores the relationship between the front slope angle and the weak interlayer inclination when the bedding rock slope slope is damaged.Combined with the finite element analysis software Plaxis 2D, multiple sets of numerical simulation tests were performed on the physical model to verify the failure mechanism of bedding rock slopes with soft-hard interlayers. …”
