分析了冻土地区护坡结构物的工作状况和受力特点，并从冻土流变性的角度讨论了块石等非整体性护坡的破坏机理，给出了块石护坡抗冰推稳定性的计算方法。提出了相应的对策。
The working conditions and stress characteristics of slope protection structures in permafrost regions were analyzed, and the failure mechanism of non-integral slope protection such as block stones was discussed from the perspective of rheology of frozen soils, and the calculation of the stability against ice shear of block stones was given. method. Proposed the corresponding countermeasures.
