Development Characteristics and Distribution of Earthquake-induced Loess Landslides in Xiji County of Ningxia Hui Autonomous Region
摘要
Abstract
Loess landslide induced by earthquake is a serious secondary disaster in Xiji County of Ningxia Hui Autonomous Region. It has special characters not only in scale but also in density, the major type of which is characterized by low angle, high speed and far distance. Xiji County is in a more active period of seismic ac- tivity at present and old landslides may easily revive in the case of continuous rain and heavy rain or earth- quake, with a serious threat to people's lives and property and severe influences to local economic construc- tion. Based on detailed field data from geological disasters surveys in the county, a classified statistic of seismic loess landslides are made by size, formation age, thickness of sliding mass and other aspects. Then the boundary characteristic, surface and inner characteristic, deformation characteristic and sliding characteristic of the landslides are analyzed. Furthermore, the spatiotemporal distribution of the landslides are summarized. The research may provide a theoretical basis for the forming mechanisms of the landslides.关键词
