摘要
双里水库建于70年代,由于当时的技术条件和历史原因,水库属"三边"工程,工程建设先天不足,运行近30年,年久失修,大坝出现多条裂缝,危及大坝安全,对其进行除险加固是必要的。经过比选,采用大坝基础帷幕灌浆、大坝上下游压载及上游干砌石、大坝高压旋喷及钻孔灌注桩防渗和充填灌浆的除险加固方案,消除了水库大坝带病运行的安全隐患。
The Shuangli Reservoir was built in the 1970s. The reservoir belongs to the ＂trilateral＂ projects due to the technical conditions and historical reasons. The engineering construction is congenitally deficient, and the reservoir has been running for nearly 30 years with disrepair. The dam has many cracks now, which endangers the safety of dam, so the rein- forcement is necessary. After comparison, the reinforcement schemes conclude the dam foundation curtain grouting, ballast upstream and downstream and dry laid stone masonry upstream, high pressure jet grouting and bored piles, filling grouting, are used, then the hidden trouble of dam is eliminated.
