| 摘 要： | 通过对粘性土进行一系列动三轴试验，测定并分析了动荷载作用下为粘性土的动剪应力，轴向应变及超孔隙水压力随时间的变化规律，分析了破坏时不同固结比的粘性土对静，动剪强度和孔隙水压力影响规律，得出了粘性土的动剪强度随固结比变化的关系式，并对粘性土的动剪强度判别方法的标准进行探讨，得出了有益的结果。 |

| Abstract: | A series of undrained cyclic triaxial shear tests were performed on normally consolidated or overconsolidated cohesive soils,which reveals the influences of consolidation ratio on the dynamic shear strength and pore water pressure. Additionally,monotonic triaxial compression tests were also performed on soil samples with the same initial test conditions. Dynamic and static strength of these soils are also compared. The relationship between the dynamic shear strength and consolidation ratio for volcanic soils are obtained. |
