The axes of the impervious curtain of toe slab foundation in Lianhua dam is located at the moderate weathering bedrock. 莲花水电站大坝趾板基础防渗帷幕,其轴线位于弱风化岩带,为了确保灌浆质量,采用了几种方法进行了质量检测。
The research result shows that the fast weathering of the red-bed mudstone slope occurs within 10 cm depth below the surface, and the variation of air temperature and the number of moderate rainfall have important effects on its fast weathering. 结果表明:红层泥岩边坡的快速风化集中在表层10cm深度内;
