| 摘 要： | 研究饱和软粘土的预剪及后固结性能，对饱和软粘土在冲击荷载作用下变形和孔压的一些规律作进一步探讨，另外，在大量试验基础上，建立了一个冲击荷载作用下孔隙水压力的计算模式，并对影响孔压发展的诸如土性、固结应力状态、荷载强度等因素进行了简要分析，试图从另一一个角度定量分析影响孔压发展的各种因素。

| Abstract: | The pre shearing and post consolidation characteristics of saturated soft clay are studied firstly. Some problems on the deformation and pore pressure of soft clay under impact loading are disscused furthermore. Based on a large number of laboratory test results, a model for expressing the pore pressure of soft clay under impact loading is proposed, and furthermore, many factors that affect the growth of pore pressure are analysed in detail, such as properties of soil, consolidated pressure state, loading magnitude, etc. |

| Keywords: | saturated soft clay pre shearing post consolidation deformation pore pressure |
