RELIABILITY ANALYSIS ON PERFORMANCE FUNCTION WITH COMPLEXITY AND HIGH ORDER NONLINEARITY IN GEOTECHNICAL ENGINEERING
具有高次非线性和复杂性功能函数的岩土工程可靠度分析

Using the improved JC method in association with an example of Hoek Brown criterion, the variables replacing technique, the compound function method as well as the rational polynomial technique are adopted in the calculation of reliability index to consider the high order nonlinearity and the complexity of the performance function in geotechnical engineering. Moreover, Monte Carlo method is employed as comparison. The results show that the method of adopting the rational polynomial technique is better than the other techniques because it is easier in calculation and more convenient in developing computer program.
