五里坝水库工程混凝土面板堆石坝设计

五里坝水库是一座采用0.3~0.67 m变厚面板的堆石坝,最大坝高67.4 m.由于坝基为软质岩、强度低,地质条件较复杂,结合工程特性,围绕减少岸坡开挖和填筑工程量,降低坝体不均匀沉降,确保良好防渗止水效果等关键问题进行详细计算分析.优化设计出满足规范要求的大坝枢纽布置、坝体分区、填筑材料和坝基处理等方案,为工程投资决策提供了重要依据.

Design of Concrete Faced Rockfill Dam in Wuliba Reservoir

Wuliba Reservoir is a rockfill dam with 0. 3 ~ 0. 67 m variable thick concrete faced panels,67. 4m high. The geologic condition of dam foundation is complicated because of the soft rock with low intensity. Combined with the project characters,the full-scale calculation and the analysis on key issues are made to ensure favorable effect in anti-seepage and sealing by reducing the slope excavation and filling engineering quantity,and the asymmetry subsiding has been restrained.After optimization and adjustment,the relative aspects,such as the concrete faced rockfill dam structure layout,the dam zoning,the dam filling material and the dam foundation treatment scheme,perfectly meet the engineering requirements,which provides an important basis for project investment decision-making.
