Reliability analysis of soil nailed structures using spreadsheet method
摘要
Abstract
It is very important to carry out the reliability analysis of soil nailed structures since there are lots of uncertainties in geotechnical engineering. Considering the function of Solver and VB programming of Excel, the spreadsheet computation model for the reliability analysis of soil nailed structures is set up. This spreadsheet model is suitable for layered soils and it can get the minimum reliability index and the location of the corresponding slip surface. The spreadsheet model is composed of five parts: module of input parameters; computation module of soil nailed structure; computation module of soil layers; computation module of reliability index and module of optimum calculation. Once the model is set up, it is very convenient to carry out the reliability analysis for different soil nailed structures. It is demonstrated that the method proposed is correct, simple and direct. It is easy to carry out the reliability analysis of soil nailed structures for different computation cases; and it can also be easily simplified to carry out the corresponding deterministic analysis.关键词
