摘要

综合利用土体动力学理论，结合弹塑性有限元分析，研究了不同地基条件、不同的夯击方式下土体的应力-应变特征，从理论上确定了不同地基条件下，强夯法施工中的设计参数选定方法，包括锤重、落距、夯距等。在常用的地基或填方参数情况下，有效加固范围是夯锤直径的1.5～2.5倍。以此作为强夯设计依据，对工程实践具有一定的指导意义。

Abstract

Based on the theory of soil dynamics and using FEM

the stress-strain relations under different ground conditions and different tamping means are studied. Compared with test results in situ

the choice of tamping factors including hammer weight

tamping height and tamping interval etc.

is established theoretically. In case of foundation and road embankment material parameter

valid reinforce range results is 1.5—2.5 of hammer's diameter. This conclusion are used for engineering practice.
