摘　　要：大庄水库是一座高坝大填筑量的心墙风化料坝,其地质情况存在煤矿采空区、库岸滑坡区、软土坝基、绕坝渗漏等主要工程地质问题。该坝为坝高76.90m的高坝,填筑量达500×104m3,为云南省同类坝型填筑量第一。设计方案采用振冲置换处理软基,采用经济合理的悬挂式帷幕防渗。Dazhuang Reservior is a high dam with large filling volume of core wall weathered material. Its geological conditions include coal mine goaf, reservoir bank landslide area, soft soil dam foundation and seepage around dam. The dam is 76.90 m high with a filling capacity of 500×10^4 m^3, which is the first of the same type of dam in Yunnan Province. The design scheme is vibro replacement for soft foundation treatment, and using economical and reasonable pensile curtain to prevent seepage.
