Probabilistic analysis of the active earth pressure on earth retaining walls for c-ϕ soils according to the Mazindrani and Ganjali method

Abstract The determination of the earth pressure coefficients (K) in geotechnical engineering is one most critical procedures designing retaining walls. However, theories are made for either clay or sands, where c-ϕ soils least analysed. In this paper, an analysis drained mixed based Mazindrani and Ganjali (J Geotech Geoenviron Eng 123:110–112, 1997) theory was carried out. Earth generally used a deterministic way can represent designs under inadmissible risk. Therefore, Reliability-based design arises as essential tool to deal with soil variability main aspects uncertainties. influence active performed through probabilistic concerning K coefficient variation (Cv) both shear strength parameters. sensitivity shows Cv which cohesion begins have more significant correlation than friction angle. results show increase statistical value slope (β) increase. Although does not significantly, on gravity walls sheet pile probability failure (p f ) p obtained be considered even if required FS met.
