泾阳南塬黄土滑坡的运动规律与液化效应
Motion Law and Liquefaction Effect of Loess Landslides in South Jingyang Plateau
摘要
Abstract
[Objective] To discuss the motion law and liquefaction effect by analyzing the motion characteris‐tics and its driving factors of loess landslides in order to provide theoretical references for hazard prevention and treatment in landslide areas .[Methods] The loess landslide in South Jingyang plateau was chosen to re‐search the motion law of landslide by site investigating ,trench excavating ,and statistical analysis .Based on the above works ,the influences of liquefaction effects on motion characteristics were discussed .[Results] According to the motion characteristics , the landslide in South Jingyang plateau was classified into two types :flowslide and slide .In the flowslide type ,the sliding distance was four times of slope height ,while the sliding distance was two times of slope height in the slide type .The minimum landslide volume that was sufficient to produce the greatest degree of liquefaction was about 1 .50 × 105 m3 in study area .[Conclusion] Greater volume and simpler sliding boundary of landslide will improve flow motion ,vice versa .关键词
