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。

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。

By means of the experimental data from dynamic triaxial stress-strain test of variable cyclic amplitude for frozen soil, the formative conditions of residual strain on frozen silt clay are studied.
