四川巫溪中阳村滑坡发生机制分析

ANALYSIS OF THE MECHANISM OF LANDSLIDE TAKEN PLACE IN ZHONGYANG VILLAGE, WUXI DISTRICT, SICHUAN PROVINCE

该滑坡在发生前,采取了及时、有效的措施,不仅避免了严重损失,并且一定程度地化害为利.在占有滑坡发生前后较详细资料的基础上,本文重点分析了斜坡变形过程和滑坡发生机制.

Before this landslide taken place, a just and effective countermeasurc was taken. Therefore there was no serious lose, even the disaster was changed to be an advantage, because the debris of landslide in valley practicaly was a well dam for hydro-electricity after repairing.On the basis of the data that before and after landslide, the author analyzed the process of the slope deformation. In the first stage there was the shearing deformation, the second stage -the compressible deformation and the fractures of shearing and compression throughout at last, the destroyed stage is the third one. The conclusion is that these factors urging the slope deformation are the disadvantageous conditions of geology and topography. The unreasonable mining of coal triggered the occurrance of the landslide.
