汾河二库增强大坝抗滑稳定性的工程措施

Engineering measures for increasing stability against sliding of Reservoir II dam

汾河二库是山西省的重点水利建设项目,拦河大坝是该水利枢纽工程的主体工程,其抗滑稳定是大坝能否安全运行的控制因素,根据其本身的特殊的地形、地质特点,采取了增设出槽、排水降压、断层挖除、固结灌浆孔插入钢筋桩等一系列措施,来提高大坝的抗滑稳定安全度,以保证大坝的安全运行。

Reservoir Ⅱ on the Fenhe River is a major project in Shanxi Province and its retaining dam is the main works of this water control project. Its stability against sliding is the control element of the dam's safety operation. According to the particular topographic and geological features, engineering measures,such as addition of cut-off trenches,reduction of pressure through drainage,removal of faults and insertion of steel bar piles in consolidation grouting loles,have been adopted to increase the dam's stability against sliding and ensure the dam's safety operation.
