茅坪与新滩滑坡体变形机理类比研究

 为了研究清江茅坪典型滑坡体稳定性，基于失稳前长江新滩滑坡实测曲线进行了滑坡体变形分析。清江隔河岩水库库岸茅坪滑坡体约有2350×104m3, 是由十分复杂的物质构成的典型滑坡体，而水库蓄水直接影响了滑坡体的稳定性;后部白岩底部采煤造成陡壁崩塌，又对滑坡体产生了巨大加载效应。通过监测茅坪滑坡体变形过程，类比长江新滩滑坡体在破坏前几个阶段的变形特征，为预测茅坪滑坡体破坏提供了有价值的参考。

Comparison of Deformation Mechanisms of Maoping and Xintang Landslide

In order to study the stability of typical Maoping landslide on Qingjiang River, on the basis of the measured curves of Xitan landslide before failure, the landslide deformation is analyzed. The analysis results show that the volume of the typical landslide on Maoping is about 2 350×104m3, which was formed by very complicated geological structure. The reservoir water has direct impact on the landslide stability. Meanwhile, a huge loading effect caused by the fall of the Baiyan cliff rock mass formed by the coal mining made the slide of the landslide more dangerous. The comparisons of several stages deformation characteristics of Xintan landslide before failure are carried out. The research results provide useful reference to predict Maoping landslide stability.
