冲击荷载下饱和软粘土孔压增长与消散规律的一维模型试验

Model Test on the Porewater Pressure in Saturated Soft Clay Soil Enduring Impact Load

一般认为 ,饱和软粘土地基不宜或应慎重采用强夯法加固 .冲击荷载作用下 ,孔压的增长与消散规律是研究强夯法加固饱和软粘土地基的基础与理论支持 ,本文就此问题进行了冲击荷载作用下饱和软粘土孔压增长与消散规律的一维模型试验 ,从试验和初步机理分析的角度来获得一些看法 .试验中考虑了不同击数 N和不同冲击能 WH的影响 。

In this paper, a one-dimensional model impact test is carried out to investigate the growth and dissapation of porewater pressure in saturated soft clay soil. Some general ideas are gotten from the analysis of the test. In the test, such factors as the impact number N and impact energy WH, are considered.
