摘要
本文通过对贵州乌江东风水电站防渗工程设计、试验研究、施工技术及防渗帷幕运行情况的介绍,尤其是对隧洞开挖遇到溶洞的回填技术,以及帷幕灌浆遇到黏土、流砂层、大裂隙、含砂溶洞、浅层半充填溶洞、深层大型溶洞等不良地质洞段处理方法的介绍,总结出岩溶地区防渗工程的施工经验,为类似岩溶地区的防渗工程处理提供了借鉴。
The paper introduces Guizhou Wujiang Dongfeng Hydropower impervious engineering design, testing study, construction techniques and impervious curtain operation condition, and especially introduces cave backfill technology encountered in tunnel excavation as well as adverse geological cave section solutions of clay, quicksand layer, large fissures, sand cave, shallow half-filled caves, deep large cave and the like encountered by curtain grouting. The paper sums up the construction experience of karst region impermeable project, thereby providing reference for impermeable project treatment in similar karst areas.
