摘要
Abstract
Wudongde Hydropower Station is located in narrow valley area with steep bank slope and high-thin dam body. Conventional consolidation grouting with cover weight could not be well conducted due to its several interferences with concrete placement and the contact grouting for dam body. Therefore two kinds of field grouting, namely"direct consolidation grouting on bedrock without cover weight" and "consolidation grouting on bedrock without cover weight plus pipe-guiding grouting for sur-face layer with cover weight" were carried out for Ⅱ and Ⅲ1 rock mass. The test results show that it is feasible to apply non-cover-weight consolidation grouting for the dam foundation. However local zones with geological defects in Ⅱ level rock mass shall be grouted with closer space and the surface layer of gradeⅢrock mass should be treated with supplementary pipe-guiding grouting.关键词
