通过室内饱和击实黄土液化试验研究 ,探讨了击实黄土孔压增长规律 .结果表明 :击实黄土在一定条件下 ,受动荷载作用能够发生液化 ;击实黄土的孔压增长曲线与原状黄土的孔压增长曲线类似 ;击实黄土在循环荷载作用下具有典型的循环软化特征 .工程上强夯处理的黄土若处于饱和或近饱和状态 ,在动荷载的作用下会发生液化并引起较大的变形
Through the indoor saturated compaction loess liquefaction test research, the compaction loess pore pressure growth law was discussed. The results show that compaction loess under certain conditions, the dynamic load can liquefaction; compacted loess pore pressure growth curve with undisturbed loess The compaction loess has a typical cyclic softening characteristic under cyclic loading.If the loess treated by dynamic compaction is saturated or nearly saturated, it will liquefy under the action of dynamic load and cause a large The deformation
