摘要

选取青藏铁路沿线粉质黏土，进行了一维土样在连续、分步两种不同冻结模式下的冻胀响应试验和数值模拟研究，得到并分析其温度梯度场及土样冻胀量的演变规律。结果表明，与连续冻结模式相比，分步冻结模式更易产生较大冻胀量，其机制主要在于该冻结模式使得冻结缘内温度梯度较大。

Abstract

Freezing tests in two different kinds of modes in the case of open system on 1D soil sample made of Tibetan silty clay are carried out

and the evolvement characteristics of the sample’s frost heave、temperature gradient field are obtained. Then according to the self-made programme based on the heat and moisture coupled frost heave model

aforementioned tests are simulated

and the result of simulation is quite consistent with the test result. Our research shows that frozen soil can make more frost heave easily under stepwise freezing modes. Our analysis makes it clear that the temperature gradient in frozen fringe with stepwise freezing mode is greater than that with continuous freezing mode.
