基于D-S证据理论的边坡稳定可靠度分析
Reliability Analysis of Slope Stability Based on D-S Evidence Theory
摘要
Abstract
Evidence theory can effectively deal with random and vague uncertain information. This paper proposed slope reliability analysis method based on D-S evidence theory. This method could not only improve the efficiency of reliability analysis,but also meet the accuracy requirements, with a strong ability to deal with uncertainty. Meanwhile,because it was not limited to the distribution of the random variable when calculating the basic probability assignment,it could overcome some of the shortcomings of traditional methods such as the random variable with arbitrary distribu-tion could not to be treated as normal distribution. It calculates slope failure probability and reliability index with examples,the calculation results of slope reliability analysis show that the method based on evidence theory is the same as Monte Carlo method.关键词
