摘要
Abstract
The carrying capacity of foundation and the seepage control of curtains in left and right banks are important part of the design of dam foundation treatment of the RCC gravity dam in Guangzhao Hydropower Station. Combined with the actual situation, the innovative design ideas are proposed to accelerate the construction of dam, including carried out consolidation grouting of dam foundation between two compacted layer construction, determining foundation rock conditions by using two criteria of the permeability ratio of grouting hole not more than 1 Lu achieved by simple water pressure test before grouting and the grout consumption of grouted hole not more than 40 kg/m, and increasing the depth of grouting holes in some area. These innovative design ideas have accelerated the speed and improved the quality of dam construction.关键词
