摘要
结合任意滑动面形式的Janbu条分法和JC的可靠度分析理论,从极限条件出发推导出可靠性分析的功能函数,给出基于Janbu法的可靠性功能函数的推导过程。根据土性参数对边坡的影响,选取土的粘聚力c和内摩擦角φ(取其正切值f)作为随机变量,并对非正态分布的c进行正态化。并根据随机场理论,分析了c、f相关性对边坡稳定可靠度指标的影响。
Based on Janbu slice method of random sliding surface form and JC reliability analysis theory, a function equation of reliability analysis is developed under limiting conditions and the development process of reliability function equation based on Janbu method is given. On the basis of effect of soil property parameters on slope, coherence and internal friction angle are regarded as random variables, and the coherence which is not normally distributed is normalized. Using the random field theory, the influence of the , correlation on reliability index is analyze.
