摘　　要：贵州省赫章县新寨水库大坝为混凝土面板堆石坝,导流洞及放空兼取水建筑物均布置于大坝左岸。根据实际情况,将导流洞、放空建筑物、取水建筑物及生态流量下泄设施结合布置,最大限度地利用了导流洞,在保证工程施工期导流度汛的同时,可以满足水库运行期放空、取水以及下泄生态流量的需求,简化了工程布置,方便工程施工,减少了工程量及施工工期,节省了工程投资,且便于后期运行管理。The dam of Xinzhai reservoir in Hezhang county of Guizhou Province is concrete faced rockfill one,and the reservoir's diversion tunnel and water empty and intake buildings are arranged on the left bank of the dam.Ac⁃cording to the actual condition,for fully using the diversion tunnel,the four buildings of diversion tunnel,empty⁃ing building,water intake building and ecological flow lowering facilities are combined,which can ensure flood re⁃lease in construction period and meet the needs of emptying,water intake and ecological flow discharge in reservoir operation period.This design can simplify engineering layout,facilitate engineering construction,greatly reduce the work and construction period,save engineering investment,and is convenient for later operation management.
