摘要

针对辽西地区的风积土进行了单向冻结试验，研究了土样在冻结过程中的温度变化规律和温度梯度对冻胀的影响；分别针对封闭系统和开敞系统进行了有外加荷载和无外加荷载作用下的冻融试验，对在一定温度条件下荷载和水分对风积土冻融性质的影响进行了试验研究，获得了温度、外荷载和水分对冻融影响及其冻融演变规律。研究结果表明，温度和温度梯度是影响土体冻胀的主要因素，而外荷载主要对融沉的演化过程和最终冻胀量产生影响，水分的迁移则主要对冻胀的演化过程产生影响。

Abstract

The one way freezing experiment has been completed aiming for aeolian soil in west Liaoning. Change rule of temperature and influence of temperature gradient on frost heave are studied in the freezing process. For the closed and opened system

freezing and thawing experiment is finished under the condition of loading and unloading. The influence of freezing and thawing character of load and moisture to aeolian soil is tested under certain temperature so that freezing and thawing rule is obtained under temperature

load and moisture. The result of research shows that both the temperature and temperature gradient is the factor of affecting frost heave. Load mainly affect the development process of thawing and ultimate frost heave. Moisture mainly affect the development process of frost heave.
