TESTING STUDY ON MECHANICAL PROPERTIES OF SLAB ROCKFILL DAM MATERIALS
面板堆石坝坝料力学性质试验研究

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.
