本文简要介绍了冻结壁稳定性的研究范围及方法,并初次用位移反分析法结合冻结壁模型试验、对冻结壁稳定性问题进行了综合研究。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。
In this paper, the research scope and method of the stability of the frozen wall are briefly introduced, and a comprehensive study of the stability of the frozen wall is carried out using the displacement back analysis method combined with the frozen wall model test for the first time. In the end, the author proposed a new viewpoint that uses the ultimate strain as a criterion for the stability of permafrost works.
