实际地震危害表明，不仅饱和的细砂、粉砂地基会产生液化，而且饱和的粉土、粉质土地基也会产生液化．文中通过对我国西北地区特殊土———黄土状土和日本的特殊土———火山灰粘性土（广泛分布于日本关东地区，且大量用于道路填土工程）进行了一系列动力三轴试验，研究了它们在动荷作用下的动力特性，孔隙水压力的变化以及动、静强度的比较，测定并分析了不同的固结比对破坏时土的动剪强度和动孔隙水压力的影响，得出了黄土状土的动剪强度随相对密度变化的关系及火山灰粘性土的动剪强度随固结比变化的关系式．
The actual earthquake damage shows that not only the saturated fine sand and silt ground can be liquefied, but also saturated silt and silty ground can also be liquefied. In this paper, we carried out a series of dynamic triaxial tests on volcanic ash cohesive soil (widely distributed in the Kanto region of Japan and extensively used in road filling works) for the special soil in the northwestern region of China --- loess and Japan’s special soil , Their dynamic characteristics, changes in pore water pressure and dynamic and static strength under dynamic loading were studied. The effects of different consolidation ratios on the dynamic shear strength and dynamic pore water pressure of soil under failure were measured and analyzed The relationship between the dynamic shear strength of loess-like soil and the relative density and the relationship between the dynamic shear strength and the consolidation ratio of volcanic clay are obtained.
