Structure and failure patterns of engineered slopes at the Three Gorges reservoir

摘要

A large number of engineered slopes have been created in the city,town and road reconstructionof the Three Gorges reservoir area. According to statistic data,the high slopes are more than 3000,and 90%are unstable that severely threat the resettlement plans. The reclamation work is distinguish and remarkable,compared to other similar projects in China. The stability-based slope utilization is considered,and the housescan be constructed at the upper,bottom,and even in the middle part of the slope. Meanwhile,the landscape shouldbe protected mostly for tourism purposes. This paper summaries the slope patterns and studies on deformationand failure mechanics. Case-studies on slope stabilization and utilization are also presented.
