| Abstract: | 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". |
