摘要

在分析土体冻胀形成原因的基础上，通过建立冻胀过程的应力场控制方程和温度场控制方程，利用固相增量法和热弹性力学理论，推导出冻胀过程中在温度场影响下的应力分量。在此基础上对冰透镜体形成条件进行了补充，提出相变温度也是冰透镜体形成的必要条件。通过对冻结过程机理的分析，在考虑温度和未冻水对冻胀量的影响基础上，对原位冻胀和分凝冻胀机理分别进行了讨论，给出完整冻胀量的理论计算方法，该方法可以更贴近描述土体实际冻胀过程。

Abstract

Based on the cause of formation of frozen heave

control equation of stress field and thermal regime is established for the frozen soil. Then

by using solid phase increment theory and thermoelasticity theory

authors attain the frozen-heave force in the frozen soil

with the consideration of the interference between stress field and thermal regime. Furthermore

phase change temperature is considered as a supplementary condition of formation for ice lens. At last

a theoretical calculation method of frozen-heave is proposed; it can exactly describe the process of frozen-heave in frozen soil

with the consideration of difference between in-situ heave and segregated ice heave.
