汾阳市董寺河治理中的雍水闸工程地质评价

Engineering Geology Assessment on the Retationable Sluices in Fenyang Dongsi River Regulation Works

董寺河(大向善-申家堡段)雍水闸主要工程地质问题是闸基的稳定、渗漏及液化,以及对工程大坝坝体稳定的影响,直接涉及到工程建成以后能否正常运行。文中通过对该雍水闸的工程地质条件分析和稳定验算、渗漏计算和液化评价,评价其对工程的影响,提出了工程处理措施,为工程设计提供了可靠的地质依据。

The main engineering geology issues of the retainable sluices of the Fenyang Dongsi River Regulation Works from Daxiangshan river section to Shenjiabao river section are the sluice foundation stability,seepage,liguefaction and the influence of above-mentioned issues on the stability of the dam body,and these issues will directly refer to whether the works can normally operate after they have been finished later. Through analying the work＇s engineering geology conditions,checking the stability calculation,seepage computation,and liquefaction evaluation,the paper accesses the impact of these results on engineering,puts forward the engineering treatment measures and provides the reliable geological basis for the engineering design.
