HUMAN-CUTTING SLOPE STRUCTURE AND FAILURE PATTERN AT THE THREE GORGES RESERVOIR

A large number of human-cutting slopes have been created since the city、town and road re-constructed at the Three Gorges Reservoir. According to statistic data, the high slopes are more than 3000, and 90% is unstable that severely threats the relocation. It is great difference with other place of China, the slopes have to be the site for the relocation at the reservoir. The stability-based slope utilization is considered, and the houses can be constructed at the upper, bottom, and even in the middle part of the slope. Meantime, the landscape sense should be protected since tourism. The paper summary the slope patterns, and analyzes the deformation and failure mechanics. Cases-study on slope stabilized and utilized is presented.
