贵州大榕古滑坡复活变形特征及滑动机制分析

Analyses on deformation characteristics and sliding mechanism of Darong revived fossil landslide in Guizhou

通过调查大榕古滑坡典型变形特征,研究了古滑体复活的滑动机制。结果表明:古滑体滑动机制为蠕滑-拉裂和滑移-拉裂。古滑坡在其特定的脆弱地质环境条件下,不仅受降雨因素影响,更与人类工程活动密切相关。

The authors analyzed and studied the sliding mechanism of the ancient landslide based on survey of the typical deformation characteristics of Darong fossil landslide. Analyses showed that, the sliding mechanism of the ancient landslide was creep-sliding and fracturing. Consequently, It was not difficult to get a conclusion that stabilization of the ancient landslide under its specific fragile geo- logical environment support was influenced not only by rainfall, but also closely related to human engineering activities.
