板岩作为堆石坝筑坝材料的工程特性试验研究

The Engineering Characteristic Test and Study of the Slate Used as Rockfill Dam Material

以老挝南欧江六级水电站南艾河料场为依托,从试验角度研究板岩等软岩类作为堆石坝筑坝材料的可行性。试验主要包括粘土矿物分析试验、长期稳定性试验、湿化变形试验、大中型剪切试验和动力特性试验。试验各项指标表明板岩作为70 m级堆石坝筑坝材料是可行的。

Based on the Nam Ai quarry site for construction of the 6 cascade hydropower projects on the Nam Ou River in Laos, the feasibility of using the soft slate as rockfill dam construction material was studied by test. The tests include the clay mineral analysis test, the long -term stability test, the wet deformation test, the large and medium shearing test and the dynamic characteristic test. All of the test indexes indicate that it is feasible to use the slate as dam construction material for a rockfill dam with a height up to 70m.
