摘　　要：董箐水电站大坝为面板堆石坝,但用作筑坝料较为成熟的灰岩料距坝址较远,而坝址处砂岩(夹泥岩)储量丰富,因此对砂泥岩进行了室内试验、现场爆破试验、现场碾压试验及坝体合理分区等的研究,解决了砂泥岩筑坝技术中的难题,为加快施工进度、节约工程投资创造了条件。The dam of Dongqing Hydropower Station is a lace rocKml one. out the mon material for building this rockfill dam are far from the dam site, and sand - mudstone is very abundant near the dam site. In order to solve the problem of building the dam using sand - mudstone, a lot of tests and studies have been carried out such as test in room, blasting and rolling test in site, research of reasonable zoning of the dam body and etc.. These tests and studies create favorable conditions for rapidly construction and cutting down engineering expenses.
