紫江水电站拦河坝原设计的重力坝方案存在地质缺陷，经补充地勘工作及综合比较，对大坝设计进行复核调整，推选出混凝土砌石拱坝为施工图设计方案。设计大坝为C15混凝土砌石抛物线变厚双曲拱坝，其对地形条件适应性好，有效解决了坝体应力及稳定问题；采用坝体自防渗，降低施工难度、缩短施工工期；为提前发电，采取分期蓄水。取得了良好的经济效益及社会效益。
紫江水電站攔河壩原設計的重力壩方案存在地質缺陷，經補充地勘工作及綜閤比較，對大壩設計進行複覈調整，推選齣混凝土砌石拱壩為施工圖設計方案。設計大壩為C15混凝土砌石拋物線變厚雙麯拱壩，其對地形條件適應性好，有效解決瞭壩體應力及穩定問題；採用壩體自防滲，降低施工難度、縮短施工工期；為提前髮電，採取分期蓄水。取得瞭良好的經濟效益及社會效益。

Geohogical defects exist in the original design of growing dam projict for Zijiang hydropowes station .After geological ex-ploration work and comprehensine comparison , adjustment to the design has been made , finally masonry arch has been recommand-ed to be the construction scheme.Because of Zijiang hydropower station of C 15 concrete masonry parabolic thick double -curvature arch dam, stress and stability problems of dam body seepage prevention has been effectively solved , construction difficult reduced , the construction period shortened;for the earlier generation , impounding in phases .Achieved good economic and social benefits .
