Finally, a new viewpoint of adopting limited strain as the major criteria of stability in frozen soil engineering is proposed.
最后作者提出了用极限应变作为冻土工程稳定性判据的新观点。
The results of triaxial creep experiments for unloading state show that the frozen soil has an obvious dilatancy, and its volume strain should not be neglected.
卸载状态下冻土三轴蠕变试验结果表明，冻土具有明显的剪胀性，且体积应变不能忽略。
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%.
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。
