摘要

基于现场动力排水固结法加固饱和软土地基工程实践和室内动力固结试验，结合土体压力分析了饱和软粘土在冲击荷载作用下的变形与孔压的发展变化规律。研究表明：冲击荷载引起土体变形和激发的孔压具有不同发展模式，土体变形与冲击击数是对数双曲线关系，而孔压与冲击击数之间仅是双曲线关系。

Abstract

Based on in site test of soft clay foundation treated with dynamic consolidation by drainage and dynamic consolidation tests in lab

the dynamic characteristics of strain and pore water pressure of soft clays under impact loading were analyzed associated with soil pressures. The study has shown that the axial strain and pore water pressures with impact number have different development models. The relationship between axial strain and impact number is of hyperbolic-logarithm function

and the development model between pore water pressure and impact number is of hyperbolic function.
