Design And Construction Of Slopes

Zipingpu Multi-purpose Dam Construction Project is located at Yingxiu-Dujiangyan reach,upstream of Minjiang river,west Sichuan. It possesses water irrigation and urban area water supply as the most benefits,and power generation,flood control,environmental protection and tourism the second. It is also listed as the No. 1 project in go-west programme by Sichuan provincial government. All water conveyance and water discharge structures are designed to locate at right bank strip ridge,due to special topography and land form. Large excavation area and steep slope raising from close plan locations of adjacent structure lead to slope stability. In general,slope stability analysis and treatment are concerns of Zipingpu project.There are large words in slope design and slope deformation analysis with monitoring involved,on basis of geology of slopes at Nos. 1 and 2 diversion tunnel inlets and actual project conditions of Zipingpu project. Interior and exterior factors and conditions causing deformation are obtained from analysis. Special measures to control deformation are taken to ensure long-term stability,such as consolidation.
