摘要
通过对黑龙江省德都县震害分析，提出季节冻土动力特性研究的必要性，在大量低温三轴实验基础上给出冻土的应力应变关系及参数、动弹模量的确定，在国内首次得到冻土动泊桑比的数值。
This paper presents that it is necessary considering dynamic characteristic of frozen soil based on analysing earthquake damage in De Du Country Heilongjiang Province This paper shows the relation between stress and strain based on a vast amount of information of low temperature dynamic triaxial shear experiment The authors also give the determination of stresss-strain parameter and dynamic elastic modulus For the first time, in China the value of dynamic Poisson′s ratio about frozen soil is given by authors of this paper
