System Reliability Analysis of Gravity Retaining Wall of Railway Embankment Based on Subset Simulation
Taking a typical railway embankment retaining wall as an example,the deterministic analysis model and results of railway subgrade gravity retaining wall were analyzed.Based on the uncertainty analysis process of subset simulation method,the correlation between random parameters and system safety factor was analyzed.Through direct Monte Carlo simulation and theoretical calculation,the re-sults of subset simulation method were compared and verified.The results show that the subset simu-lation method can greatly reduce the calculation consumption and ensure the calculation accuracy.
