冻融循环条件下武汉红土物理力学性质试验研究

2008年我国南方出现了历史上罕见的"低温雨雪冰冻"天气,由于土体冻融破坏,产生了很多地质灾害。而在土体冻融过程中,温度和含水量具有重要的影响。通过对取自武汉市汉阳地区的红色黏土进行不同含水量下的冻融循环试验,并连同原状土一起,进行了一系列土体物理性质和工程力学性质变化规律的研究,以验证冻融过程对土体强度的影响。

Experimental Studies on Red Clay Soil in Wuhan under Freeze-thaw Cycle Condition

In the year of 2008,China was hit by exceptionally severe disaster of low temperature,rain and snow,and freezing weather.The freezing-thawing deterioration of soil led to many geologic hazards.During the freezing-thawing action of soil,temperature and water content have import influence.The red clay soil from Hanyang in Wuhan is tested under freeze-thaw cycle condition with different water contents,and,together with the in-situ soil,a series of studies are carried out on the physical property and mechanic property of the soil,which proves that the freezing-thawing action has important influence on the strength of red clay soil.
