Reliability analysis of geosynthetics reinforced soil wall

This paper examines reliability analysis for GRSW (Geosynthetics Reinforced Soil Wall). Proposed analysis method evaluates stability of GRSW against six failure modes with uncertainty of the design parameter. Performance functions needed for the analysis are derived from the design manual for GRSW of Japanese Public Works Research Institute. Compared failure probability calculated by proposed method, the most critical failure mode can be evaluated. In this paper, outline of the analysis method is explained, and advantage of reliability analysis is discussed on the basis of numerical results for simple condition.
