驮英水库泄洪建筑物方案比选

Comparison and selection of flood-relief structure schemes for Tuoying Reservoir

驮英水库需进行泄洪建筑物方案布置比选,首先采用“单独溢洪道”与“溢洪道+泄洪洞”联合泄洪等两种泄洪方式从结构安全、运行调度、防汛抢险、工程投资等方面进行比选,确定“溢洪道+泄洪洞”联合泄洪的泄洪方式。从结构安全、运行调度、防汛抢险、工程投资等方面对“左岸溢洪道”及“右岸溢洪道”进行方案比选,最终确定水库的泄洪建筑物的布置方案。

For the design of flood-relief structure of Tuoying Reservoir,the joint flood discharging scheme consisting of overflow spillway and spillway tunnel was selected after it was compared with the single overflow spillway alternative in respects of structural safety,operation and control,flood protection,construction cost etc.,based on which left bank spillway scheme was compared with right spillway alternative in respects of structural safety,operation and control,flood protection,construction cost etc.before the layout scheme was determined finally.
