摘要
以湖北宜昌桂花园水电站大坝工程为例,对坝型方案进行比选,确定上坝线混凝土重力坝为最终方案,并计算出坝顶高程606.80m,确定坝基和坝肩分别采用固结灌浆和帷幕灌浆处理。通过计算得出该设计的坝基抗滑稳定性满足要求。
Taking the dam project of Guiyuan Hydropower Station in Yichang,Hubei Province as an example,this paper first compares the dam type schemes,determines the concrete gravity dam on the upper dam line as the final scheme,and calculates the dam crest elevation of 606.80m,and determines that the dam foundation and abutment are treated by consolidation grouting and curtain grouting respectively. Finally,the calculation shows that the anti-sliding stability of dam foundation meets the requirements under this design.
