剪切强度是冻土的重要力学性能指标之一，它为工程勘察设计评估和计算承载力提供了基础。冻土的抗剪强度是冻结土的极限剪切破坏，在计算承载能力、稳定性、冻土基础、冻土墙土压力和冻土边坡稳定性评价等都需要冻结土的抗剪强度指标。本文对冻土抗剪强度试验方法进行了研究与分析，分析了每种试验方法的试验原理以及相关试验，并提出了每种试验方法的优缺点，为以后开展冻土剪切特性的试验研究提供参考。%Shear strength is an important mechanical prop-erties of frozen soil, which provides the basis for engineering survey and design evaluation and calculation of bearing capacity. Frozen soil shear strength is the ability to freeze the soil to resist shear failure, stability, permafrost foundation, permafrost and permafrost soil pressure wall slope stability evaluation, etc. are required to freeze the soil shear strength index. This paper on the frozen soil shear strength test method are analyzed and stud-ied, analyzed the testing principle of each test method and asso-ciated test, presentsed the advantages and disadvantages of each test method, provided the reference for the experimental re-search carried out after the shear characteristics of frozen soil.
