Study on Engineering Characteristics and Deformation of Yima Loess Landslide of Yinchuan-Xi’an Railway
摘要
Abstract
Yinchuan-Xi’an Railway passes through loess flat-topped ridge replat and gully area, and adverse geological phenomena are common. The engineering geological condition of the landslide is identified though field survey, drilling and laboratory soil test. Yima landslide is a large deep loess ancient landslide, the front part of the landslide is suspended and developed scarps are on the rear part with loess settlement caves on tableland behind landslide and gullies on side edge. The landslide is affected by human activities such as irrigation and drainage. The engineering characteristics and deformation law of landslide are studied by means of formation macroscopic evaluation, physical parameters analysis of soil mass and finite element numerical simulation, and the potential landslide hazards are evaluated to provide references for railway line selection.关键词
