Reliability Aanalysis of Internal Stability of Soil Nailed Structures

摘要：

The general form of the limit state function for the reliability analysis of internal stability of soil nailed structures is given, and the gradients of the limit state function with respect to basic variables can be calculated by numerical methods. Considering modes of the combination of the method of reliability analysis and the method of the stability analysis, two methods of first order reliability analysis for soil nailed structures are proposed, and their flow charts are designed. Based on these flow charts, the program is compiled in VISUAL FORTRAN 6.5. The features of these two methods are reviewed and their applicability and accuracy are proved by a sample problem of a deep excavation.
