摘　　要：扎实德水库坝体堆石料为硬岩与软岩混合料,且硬岩软化系数较低,文中根据其料源情况,研究其渗透性、变形、力学特性,合理进行大坝分区设计,并提出大坝的填筑标准,有效控制坝体变形量,避免坝体产生裂缝,确保工程安全运行。The rockfill dam of the Zashide reservoir is hard rock and soft rock mixture,and hard rock softening coefficient is low.According to the material source,this paper studies the permeability,deformation and mechanical properties,rationally designs the dam zoning,and puts forward the filling standard of the dam,so as to effectively control the deformation of the dam,avoid the crack of the dam,and ensure the safe operation of the project.
