通过对不同围压、频率、温度和含水量冻土体的测试结果分析得出,动荷载下冻土体的弹性模量受温度影响最大,随温度升高而降低,随围压波动起伏,随振动频率增大而增大。冻土体的动阻尼比随频率的增加或温度的降低而减小。应变速率在土体变形初始比较大,而后逐渐趋于稳定。 According to the test results of frozen soils with different confining pressure, frequency, temperature and water content, the elastic modulus of frozen soils under dynamic loading is the most affected by temperature, decreases with the increase of temperature, fluctuates with the confining pressure, As the vibration frequency increases. The dynamic damping ratio of frozen soil decreases with increasing frequency or decreasing temperature. Strain rate in soil deformation initial relatively large, and then gradually stabilized.
