基于系统分析的露天矿滑坡体系可靠度评价

应用系统分析理论对露天矿边坡多滑面组成的滑坡体系进行了可靠度评价，避免了只用一个最危险滑面的可靠指标来评价整个边坡系统安全性所引起的较大误差。在可靠指标的求解过程中，引入了有理多项式技术，解决了隐式求导的问题。把这种方法运用到某露天矿工程边坡上发现，整个系统的失效概率和最危险滑面失效概率之间的差异是非常明显的。因此，在地质奈件复杂地区，用系统分析的观点考察整个滑坡体系的可靠度才能确保工程的整体安全性。

Reliability Evaluation of Landslip System in Open-pit Based on Systems Analysis

The reliability of landslip system in open-pit with several slide surfaces was evaluated by applying the theory of systems analysis and a reliability interval was presented.Consequently,the bigger error caused by substituting the stability index of critical surface for that of overall slope system was avoided.Additionally,in the process of calculating reliability index,the rational polynomial technique was introduced to solve the derivative problem of non-linear and inexplicit performance function.The pract...
