摘要两个斜坡进行了概率分析，强调的见解和灵敏度信息可从设计点的一阶可靠性方法（FORM）。第一个案例是旧金山弗朗西斯科湾泥的水下斜坡，在挖掘过程中失败。第二个个案是香港一个被鉴定为潜在不稳定的岩石斜坡。介绍了基于FORM的可靠性分析和基于可靠性的设计（RBD）的见解，并讨论了RBD克服部分因子设计方法的一些局限性的能力。
ABSTRACT Two slopes are analysed probabilistically, emphasising the insights and sensitivity information obtainable from the design point of the first-order reliability method (FORM). The first case was an underwater slope in San Francisco Bay Mud that failed during excavation. The second case was a rock slope in Hong Kong which had been identified as being potentially unstable. Insights from FORM-based reliability analysis and reliability-based design (RBD) are presented, and RBD’s ability to overcome some of the limitations of partial factor design approaches are discussed.
