摘要
Pengyang County is the most serious county that bears landslide hazards in loess areas. These hazards have a serious threat to life and property of local people and hinder social and economic development. Based on detailed field data from geological disasters surveys in Pengyang County, firstly, a classified statistic of loess landslides are made by size, formation age, thickness of sliding mass and other aspects, then the distribution rules of loess landslides is analyzed, combining with remote sensing interpretation and field survey results; Secondly, topography, lithology, rainfall, groundwater, surface water and human engineering activity that influence loess landslides are analyzed. Finally, the relationship between loess landslides and main factors are simulated by GEO-SLOPE software. Based on all above, the formulation mechanism of loess landslides in Pengyang County is discussed.
