摘要

基于广义强度准则，提出了一种评价地基土换填抗冻胀能力的新方法。将冻胀力作为外载荷考虑，将冻土缺陷考虑为裂纹，并把冻土断裂韧度作为重要因素引进新准则。通过一个挡墙基础的算例，对换填前后的稳定性和强度进行了分析，与传统方法相比，由于考虑了更多的因素，从而更加合理。

Abstract

Based on a generalized strength criterion

a new method is presented to evaluate the ability of anti–frost-heave ability via the replacement of ground soil. Compared with the conventional methods

the criterion proposed is more reasonable since more factors are taken into account. The frost-heave force is considered as a kind of external load

and the defects of frozen soil are treated as cracks. The toughness of frozen soil

as an important factor

is introduced in the new criterion. A numerical example of a retaining wall is given to analyze the stability and strength before and after replacement.
