摘　　要：贵州省赫章县新寨水库大坝为混凝土面板堆石坝,大坝枢纽区河谷地形不对称,左岸陡峭而右岸覆盖层较深,枢纽区建筑物的布置空间有限。根据实际地形地质条件,合理进行大坝枢纽区建筑物的布置以减少工程量及投资、加快工程施工进度,对大坝筑坝材料分区、溢洪道布置以及导流兼取水放空洞综合布置进行了优化设计。本文系统介绍了新寨水库面板堆石坝材料分区、枢纽建筑物布置、细部结构设计等内容,可供同类工程设计、施工参考。The dam of Xinzhai Reservoir in Hezhang County is a concrete face rockfill dam.The topography of the river valley in the dam functional region is asymmetrical;the left bank is steep and the overburden layer of the right bank is deep,so the layout space for the buildings in the functional region is limited.In order to reduce the project quantity and investment and speed up the construction progress,the reasonable layout of the buildings in the functional region is designed according to the actual topographic and geological conditions,and the construction material division,spillway layout and diversion tunnel layout are optimized.This paper systematically introduces the material division,building layout and detailed structure design of the concrete face rockfill dam of Xinzhai Reservoir,which can be used for reference in the design and construction of similar projects.
