| 摘 要： | 通过大量室内试验，研究饱和软粘土在冲击荷载作用下的变形和孔压增长规律，讨论孔压增长的内在机理和不同围压、不同冲击能作用下孔压量的变化。讨论土体的再团结变形规律，提出再固结体积压缩系数的确定方法。最后分析冲击荷载作用后的强度变化。这些讨论为动静结合法处理软基提供了依据。

| Abstract: | Based on a large number of laboratory test results, the deformation characteristics and the growth of pore water pressure in soft clay under impact loading are studied, and the quantitative change of pore pressure with various values of confining pressure and impact energy is also discussed. The re-consolidation deformation law of soil is analysed and a method of determining coefficient of volume compressibility is suggested. Finally, the change of shear strength of soft clay after impact loading is analyzed briefly. These discussions provide some useful conclusions for the treatment of saturated soft clay by the drainage consolidation method of combing static and dynamic loading. |
