泗南江水电站混凝土面板堆石坝设计及实践

Design and practice of concrete faced rock-fill dam of sinanjiang hydro-power station

泗南江水电站装机容量201MW，面板堆石坝最大坝高115m，枢纽区断裂构造发育，岩石软硬相间，性状较差的1#崩塌堆积体位于左岸坝轴线下游主堆石区基础，地质条件复杂，设计难度大。本文较全面论述了泗南江水电站面板堆石坝设计重点及相关技术应用、运行检验，对相关坝型设计具参考价值。

Sinanjiang hydropower station has an installed capacity of 201MW and the maximum height of concrete faced rock-fill dam is 115m. Fault structures are developed in the interior and hardness of rocks are identical. Falling accumulation 1# with poorer property is located on the foundation of rock-fill area on the left side of the downstream of dam axis, where the complexity of geological condition posed a difficulty to design. This paper discusses comprehensively on the design focus, application of relative technique and inspection, providing experiences to the design of dam with similar mode.
