摘要
王家沟水库是冯家山水库北干渠上6座渠库结合工程之一,集输水、道路、蓄洪为一体,功能多、作用大,水库的安全运行特别重要。本文对该渠库结合工程中存在的坝体不稳、坝肩渗漏、坝顶输水渠渗漏、溢洪道新建和进水道改造等典型病险危害进行了分析,并对加固方案及措施作了比较,据此提出了坝体压脚、坝肩水泥帷幕灌浆、顶渠铺膜防渗等加固方案。王家沟水库的成功加固,对黄土地区渠库结合工程的土坝除险加固具有典型的参考意义。
Wangjiagou Reservoir is one of the six combined engineerings of channel and reservoir in north main channel of Fengjiashan Reservoir.It has many functions,such as water conveyance,road,and flood storage.So it is very important to keep the reservoir running safely.The typical dangers are analyzed here including instability of dam body,leakage of dam shoulder,leakage of water conveyance channel of the dam top,newly built spillway,transformation of infall and so on.Based on the comparison of reinforcement schemes and measures, several appropriate reinforcement measures are proposed, i.e. pressing stand for the dam body, curtain grouting using cement for the dam shoulder, plastic film mulching for the top of the channel and so on. The measures as mentioned above can provide references for danger control and reinforcement of the combined engineerings of channel and reservoir in loess areas.
