Development Pattern of Toppling Deformation Slopes in Western China

Controlled by regional geological background, and affected human activity weathering, toppling deformation slopes occur in different regions China. Based on statistics about domestic their distribution, the susceptibility zonation area of was determined. Firstly, a evaluation conducted according to these slopes, choosing landform, stratigraphic age, seismic intensity tectonic stress study divided into very low, medium, high areas. Secondly, geographic position aimed at sections typical rivers western China related them, upstream, midstream downstream 11 that were respectively classified Thirdly, based results, associations between factors (lithology, slope height, elevation, horizontal depth vertical depth) distribution revealed. Finally, development regularity analyzed comprehensively. The results show hydropower projects are more developed Sichuan, Qinghai Yunnan provinces With regard geography, besides Yellow River, both Lancang River Yalong flow through areas with as highly susceptible zones all levels. this can be used references for site selection plans projects.
