In order to find out the mechanism of the soil strength weakening during the period of thawing and the effective prevention measures , some adjustment was made on the traditional triaxial apparatus , together with special frozen soil samples preparation equipment , customized frozen soil samples thawing apparatus and external heat preservation facilities , a new apparatus for investigating the weakening characteristic of frozen soil was made successfully 为探明路基土融化过程中的强度弱化机理,在此基础上制定有效的冻害预防措施,对国产土工静力三轴仪进行了一系列改造,并配以专用的冻土试样制备设备、冻土试样融化加热设备和外部保温设施,共同制成冻土解冻时的强度弱化试验仪。
