在大庆地区采取了千余个季节冻土的原状土样进行室内融化压缩试验。依据使用特点,试验采用两种方法:一是先融化后压缩,二是融化与压缩同时进行。试验表明,两种方法的试验结果有一定的差异。季节冻土和多年冻土之间的融化压缩特性具有良好的共性关系,但它们之间亦有一些差异,工程设计选值时应予足够的注意。 In Daqing area taken more than a thousand season of frozen soil original shape of indoor melt compression test. According to the characteristics of the use of the test using two methods: First, after the first melt compression, the second is melting and compression at the same time. The experiment shows that there are some differences between the two methods. Melting and compressing characteristics between seasonal permafrost and permafrost have a good common relationship, but there are also some differences between them, engineering design and selection should pay due attention.
