RELIABILITY ANALYSIS FOR REINFORCED SOIL WALL WITH SESMIC HAZARD INFORMATION

Abstract

Reliability analysis method for reinforced soil wall with seismic hazard information was examined. In the parent paper, outline of the method are shown and effects of design value uncertainty, reinforcements layout and seismic hazard information is considered based on analysis results. Established results are as following. (1) The developed method evaluates stabilities against six failure modes with considering uncertainties of design values and seismic load. (2) Effects of uncertainty for design values of backfill soil is more enormous than that for reinforcement (3) Effects of reinforcements layout depends on type of failure mode. (4) In the case that stronger seismic load is assumed, failure probability for sliding or overturning of reinforced zone becomes larger.
