为了保证红寺堡水源工程大坝安全，对坝体填筑土料的物理力学性质进行了测试，结果：库区土以粉粒为主，部分探井的粘粒含量小于10%；在不同压实状态、饱和状态下剪切试验结果有所不同，应分别取值，压缩试验均属中等偏低压缩性土；当压实度增加0.01时，渗透系数较压实度为0.96时高1.59～6.18倍，均在1.0×10-5 cm/s的数量级，满足小于1.0×10-4 cm/s的规范要求。

In order to ensure the main dam safety of Hongshibao Water Source Project, tests were conducted to in?vestigate the physical and mechanical properties of soil material to be used for dam construction. The results of test demonstrate that soil material in reservoir area is silt predominantly;the percentage of clay silt in some test wells is less than 10%;the results of shear test vary under different compaction or saturation states. It is concluded that the soil is moderately low compressible soil. The permeability coefficient increases by 1.59~6.18 times when the com?paction degree increases by 0.01 based on a degree of 0.96, but all within the magnitude of 1.0×10-5cm/s, conform?ing to the requirements of less than 1.0×10-4cm/s.
