机械扰动后，粘土和砂砾土受水侵蚀影响相差不多，但在风蚀情况下，砂砾土抗风蚀能力远强于粘土。

After the the soil is disturbanced by machinery , the clay be effected as same as the gravel soil by the water erosion , but gravel soil erosion resistance is far better than clay ability by the wind erosion . 3 .

传统经典振动孔压模型一般根据砂土试验得到，不能直接应用于粘性土、砂砾石土等土料的振动孔压计算当中。

Some of the traditional classical vibration pore pressure models were obtained based on the testing of sand , which cannot be directly applied to seismic pore pressure computation of the cohesive soil and gravel of high earth-rockfill dam .
