依据土体应力状态、计算边坡稳定安全系数的思想，结合对土体根本性质的认识，对基本假定、公式推导过程和工程应用进行了详细的说明。由于土坡稳定安全系数的计算公式在理论分析依据是严密的，推证得到的计算公式是正确的，所以在工程实用是可靠的。文章为该方法的工程应用和深入开展相关的研究奠定坚实的基础。

According to the soil stress state and calculation method of slope stability coefficient, and combined with soil properties, this paper illuminated basic assumption, formula derivation process and project application in detail. As the calculation formula of slope stability coefficient's theory analysis is rigorous, and the derived formula is correct, the project application is reliable. This paper will provide reference for relative project application and further research.
