| 摘 要： | 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。 |
| 关 键 词： | 击实黄土 孔压模式 循环软化 |

| Abstract: | The increasing rhythm of pore water pressure and cyclic softening behavior is discussed by tests on saturated compacted loess. The results indicate that saturated compacted loess can liquefies subjected to dynamic loads,the curve of pore water pressure of it is similar to that of initial loess,and it displays softening nature subjected to cyclic loads. In engineering,reconstituted loess,if it is saturated or almost saturated,can liquefies and deforms strongly. |
| Keywords: | Compacted loess Pore water pressure increasing mode Cyclic softening |
