| 摘 要： | 在岩土工程设计中，抗剪强度参数c、φ值是必不可少的两个指标，比如在边坡支护及稳定性分析、基坑支护，甚至在分析黏性土的承载力特征值时都可以用来作为一个重要的参考指标。本文认为内摩擦角φ的正切值（tgφ）等效于物理学中的摩擦系数μ。基于此，浅谈一下对c、φ值的理解。

| Abstract: | In the geotechnical engineering design, shearing strength parameters, C and φ are two indicators essential, such as in the slope stability analysis, supporting and retaining structure of foundation pit, and can be used as an important reference index even in characteristic analysis of bearing capacity of cohesive soil. I personally think that the value of tg φ （φ： the internal friction angle） is equivalent to μ（the friction coefficient in physics）. Based on this, I talk about my understanding on C and φ . |
