摘要: 笔者从分析抗滑桩的破坏模式入手,运用Rosenblueth法计算滑坡推力、桩身承受的弯矩、剪力、桩的设计强度、嵌岩深度等中间变量的均值、标准差以及各功能函数的均值和标准差,假定各功能函数中的参数均符合正态分布,计算出抗滑桩的失效概率.
关键词: 滑坡推力, 极限状态, 随机变量, 可靠指标
Abstract: Based on analysis on failure state of piles for resisting slide, athor calculated the average values and variations of middling variables with Rosenblueth method. Such as slide thrust, winging moment and shearing force, the design intensity of pile, the nuzzling into rock depth, functions and so on. Assuming that variables obey normal, failure probability of piles for resisting slide was analyed.
Key words: slide thrust, limit state, random variable, reliability index
