岩门子水库枢纽平面布置及泄洪建筑物设计

Design of the General Layout and Flood Discharging Structures of Yanmenzi Reservoir

岩门子水库坝址区地质条件较复杂,坝基软质岩体均匀性较差,且存在高边坡等问题,并综合考虑泄洪消能条件、施工条件、筑坝材料等因素,设计优选了面板堆石坝枢纽方案。根据大坝布置及左右岸地形地质条件,对泄洪建筑物的布置及结构进行了对比分析,优选了竖井旋流泄洪洞方案。

In the dam site of Yanmenzi Reservoir,complex geological conditions such as soft foundation rock with poor uniformity and high slopes are encountered.Considering the flood discharging and energy dissipation conditions,construction conditions and construction materials,the concrete face rockfill dam is selected.Then,according to the layout of the dam,and topographical and geological conditions of the left and right banks,different schemes of the arrangement and form of the flood discharging structure are compared.The vertical rotary flow discharging tunnel scheme is then adopted.
