摘　　要：某水电站大坝由于料区植被覆盖层被剥离,无泥土层,导致料区岩体出现宽度在35.0m左右的强风化岩层,且夹层内岩石完全被粉末化,导致该水电站大坝碾压混凝土中夹杂了一定量的强风化岩粉。为确定强风化岩粉对水电站大坝混凝土砂浆性能的影响,文章采用试验探究的方法,结合某水电站大坝碾压混凝土施工设计情况,探究了强风化岩粉对水电站大坝混凝土砂浆性能影响,以期为水电站大坝碾压混凝土施工中强风化岩粉的有效控制提供依据。Due to the stripping of vegetation cover layer and the absence of soil layer in the material area of a hydropower station,the rock mass in the material area has a highly weathered rock layer with a width of about 35.0m,and the rock in the interlayer has been completely powdered,resulting in a certain amount of strongly weathered rock powder mixed in the RCC of the dam of the hydropower station.In order to determine the strongly weathered rock powder effect on the performance of hydropower station dam concrete mortar,this paper adopts the method of experiment to explore,combines the condition of a hydropower station dam RCC construction design,explores the strongly weathered rock powder influence the performance of hydropower station dam concrete mortar,for hydropower station dam RCC construction of strong weathered rock powder which provides the basis for the effective control.
