鲁布革电站堆石坝防渗体原选用下游红土料与风化白云岩的掺合料,由于运距远,土料含水量高,施工难度大且不经济。后取风化料作室内物理力学试验,并经现场29场碾压试验,确定了风化料作高土石坝防渗体的施工工艺流程和主要施工参数。1986年2月用于坝体一部分的高水围堰施工中,用风化料填筑围堰斜墙9.37万m~3,1987年主坝心墙风化料填筑8.09万m~3,填筑高度约34m。
As the admixture of downstream red earth material and weathered dolomite, the impermeable body of the Ruibuji Hydropower Station rock-fill dam is difficult to construct because of its long distance and high soil moisture content. Weathered material for indoor physical and mechanical testing, and by the scene 29 rolling test to determine the weathering material for high embankment dam seepage body construction process and the main construction parameters. In February 1986 for the construction of high water cofferdam part of the dam, weathered cofferdam cofferdam inclined wall 93,700 m ~ 3, in 1987 the main dam core wall weathering material filling 80,900 m ~ 3, filling Height of about 34m.
