摘要
Abstract
In the reinforcement design for Liufengshan Reservoir dam, the tallest earth dam in Guangxi , we selected a seepage control scheme of plastic concrete core wall in the light of the engineering geological conditions and characteristics of the earth dam. Moreover, inadequate filling compaction quality and large sand content of the dam usually resulted in hole collapses during the construction of the impermeable plastic concrete core wall. We adopted a series of countermeasures, including increasing the slurry' s density and adding sawdust in the slurry, filling grouting, and high-pressure rotary jet grouting. In addition, we described the construction program of plastic concrete core wall and the selection of construction machinery used in the project. It could be taken as reference for similar projects.关键词
