Probabilistic stability analysis of Bazimen landslide with monitored rainfall data and water level fluctuations

Wengang ZHANG, Libin TANG, Hongrui LI, Lin WANG, Longfei CHENG, Tingqiang ZHOU, Xiang CHEN

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 5,   Pages 1247-1261 doi: 10.1007/s11709-020-0655-y

Abstract: It is widely accepted that rainfall and periodic variation of water level are the two main factors triggeringThe results indicate that the fluctuation of the reservoir water level plays a pivotal role in inducingslope failures, for the minimum stability coefficient occurs at the rapid decline period of water levelThe probabilistic analysis results reveal that the initial sliding surface is the most important areaThe seepage calculations from probabilistic analysis imply that rainfall is a relatively inferior factor

Level set-based isogeometric topology optimization for maximizing fundamental eigenfrequency

Manman XU, Shuting WANG, Xianda XIE

Frontiers of Mechanical Engineering 2019, Volume 14, Issue 2,   Pages 222-234 doi: 10.1007/s11465-019-0534-1

Abstract: In this study, we develop an isogeometric analysis (IGA)-based level set model for the formulation andThe proposed method is based on a combination of level set method and IGA technique, which uses the non-uniformrational B-spline (NURBS), description of geometry, to perform analysis.The same NURBS is used for geometry representation, but also for IGA-based dynamic analysis and parameterizationof the level set surface, that is, the level set function.
