黄土台塬滑坡特征及形成机制分析

1968年盐锅峡水库蓄水后，改变了库区原来的水文地质条件，导致处在盐锅峡和八盘峡库区之间的黑方台滑坡日益频繁。据不完全统计，1968--2009年该台塬边坡地带共发生过100多次滑动。针对由水库蓄水诱发滑坡的情况，分析了黑方台的地质环境特征，重点分析了黑方台黄土塬边滑坡的分布特征、类型特征、形貌特征、结构特征及成因特征．最后对滑坡的形成机制进行初步探讨。对防治由水库蓄水诱发滑坡有一定的参考价值和意义。

Features and formation mechanism analysis on loess landslide

Since Yanguoxia Reservoir stored water in 1968,the original hydro-geological condition has been changed that led to frequent landslides in Heigfangtai laid between the reservoir areas of Yanguoxia and Bapanxia.According to incomplete statistics,there were more than 100 landslides happened in Taiyuan Slope section from 1968 to 2009.The analysis is focus on landslide distribution,types and morphological features,pattern and reasons.A preliminary study is made to the formation mechanism of landslide which is o...
