Experimental Study on Retaining Walls with Narrow Cohesionless Backfill Using Arching Theory
Publication: Geo-Congress 2020: Engineering, Monitoring, and Management of Geotechnical Infrastructure (GSP 316)
ABSTRACT
Arching effect causes reduction in earth pressure in retaining wall with narrow backfill which magnifies the need to study actual characteristics of such walls. In this study, series of load displacement/settlement tests on small scale model of narrow RE wall were conducted under static footing loading condition to investigate the effect of lateral displacement, settlement, distribution of lateral earth pressure, and mobilization of tension at each reinforcement layer. Performance evaluation was based on active earth pressure condition where variable parameters include interface connection between narrow RE wall and existing stable wall, footing offset distance, and relative density of sandy soil. Result demonstrated that coefficient of lateral earth pressure decreases as depth of narrow RE wall increases indicates arching effect takes place because of mobilization of soil-wall friction angle developed along the side walls. Also, provision of interface connection helps decrease in lateral displacement by 0.6–0.8 times in upper layer and generates additional frictional resistance to combined wall systems.
