摘要
Abstract
The geological condition of Xiangjiaba Hydropower Station is complicated with main geological defects of the fracture belts at deflection core area , the compressed fracture belts and the soft interlayer .The design method of dam foundation treatment is presented from three aspects of foundation surface selection , seepage control design and reinforced grouting of foundation .Es-pecially, according to the contradiction of foundation lift force and foundation seepage stability , we have proposed a solution of controlling drainage system innovatively , i.e., setting valves in the drainage outlets of the dam foundation to adjust the drainage volume according to the monitoring data in the initial reservoir impoundment .关键词
