Description
Summary:Based on the high resolution remote sensing images of Qianjiangping landslide, applying the technique of digital landslide and man-machine interactive interpretation, by way of analyzing geomorphologic features shown the Qianjiangping slope is an along-bedding paleo-landslide, "7.13" landslide is a large-scale along-bedding reactive landslide. The displaced volume is 1.5times10 7 m 3 . Synthetically analyzing the process of slide and the characteristic of deposit, it is concluded that the middle and front part of Qianjiangping landslide is push-type sliding and the back part is drag sliding, the main triggering factors was the first stage storage the Three Gorges, the continuous rainfall make some effect.
