面板堆石坝坝料力学性质试验研究
|
摘要
宜兴抽水蓄能电站初步设计为面板堆石坝。进行室内试验,研究堆石料的物理力学性质与级配、密度、泥岩含量的关系。试验结果表明,堆石料的最大干密度需用振动台试验获得。压实堆石料具有强透水性、低压缩性、破坏应变低、抗剪强度高。各料场级配石料均能够作为面板堆石坝的筑坝材料。在进行了不同级配和泥岩含量的堆石料试验基础上,统计分析了各力学参数与泥岩含量的关系。
The dam of Yixing pumped-storage hydroplant is a slab rockfill dam. The laboratory tests were made on the relation among gradation,density and content of mudstone and the physical and mechanical properties of rockfill material. The testing results show that the maximum dry density of rockfill should be tested by theplatform vibrator. The compact rockfill materials are of the properties of high permeability,low compression,low failure strain and high shear strength. The graded material could be used as rockfill material. The relationships betweenthe mechanical characteristics and mudstone content are statistically analyzed according to the testing results.
