汾河二库大坝灌浆工程的施工方法

On Construction Method of Dam Foundation Grouting in Second Fenhe Reservoir

汾河二库大坝为碾压混凝土重力坝,坝址位于悬泉寺背斜的南西倾伏端F9断层与F10断层之间,坝基岩溶发育微弱,以溶孔和溶蚀裂隙为主,两坝肩岩溶较发育。为保证大坝的安全和蓄水量,须对坝基、坝肩进行固结灌浆和帷幕灌浆。文中就汾河二库大坝灌浆工程主要施工方法的一些经验进行探讨。

The Second Fenhe Reservoir＇s dam is a roller compacted concrete dam. Its site is located on the southwest plunging side of Xuanquansi anticline and between the F9 fault and F10 fault .The karstification in dam foundation is faint and the main forms are solution hole and fissure ,but in dam abutment it is strong .In order to guarantee dam safety and water storage, the curtain and consolidation grouting must be conducted. In this paper ,the main construction method and experiments about dam foundation grouting in second Fenhe Reservoir are discussed.
