【摘要】 冻土的回弹动弹模,在土体应变过程中为非定值,应变大于1%之后趋于稳定,并随测定时的应变速率加大而变大。振动频率对回弹动弹模有一定影响,高振频使测定值有所下降。更多还原

【Abstract】 In the process of deformation of frozen soil, the unloaded dynamic elastic modulus is not constant, and tends basically to steady after the strain is more than 1%. Elastic modulus increases with increasing in strain rate selected by test. Vibratory frequency has some effect on measured value of the unloaded dynamic elastic modulus. Higher vibratory frequency may decrease a little the value of the modulus.更多还原
