摘　　要：土石坝坝坡抗滑稳定分析,以概率设计准则为基础,以可靠指标度量结构可靠性,采用以基本变量的标准值和分项系数表达的极限状态实用设计表达式进行设计,称分项系数设计法。介绍了5个分项系数和稳定分析公式,对引入的"相当安全系数"做了说明。The analysis of earth rockfill dam slope stability against slide is based on probability design principle and measuring the structure reliability by reliability indexes. The design by use of standard value of basic variables and the design expression of limit state expressed by partial factor is called as partial factor design method. The paper presents 5 formulas of partial factors and stability analysis and describes the introduced ＂relative safety coefficient＂.
