陕西省泾阳南塬崩塌、滑坡地质灾害及成因分析

Geological Hazard of Cliff Collapse, Landslide and Their Occurrence in Southern Jingyang County of Shaanxi Province

泾阳南塬崩塌、滑坡带是关中地区黄土台塬地质灾害的典型代表。分析了该类灾害的分布规律及形成过程,结果表明活动构造、地震、地貌、地层岩土、河流侵蚀是该区地质灾害形成的基础,人类过度扰动及灌溉是其形成的诱因。提出该类预防总体应以避让为主,局部兼以工程治理。

A conclusion is drawn that, in southern Jingyang County in Shaanxi Province, active conformations, earthquake faults, rock and soil layers and river erosion are the primary cuases of geological hazards. Intense human activities, particularly irrigation, also contribute to it. After analyzing the distribution and formation processes of cliff collapse and landslide, which are typical geological hazard phenomena in the loessial highlands in Guanzhong area of Shaanxi Province, prevention measures and predictions methods are put forward.
