Title: LRFD Example Problem 2 – CIP Wall with Sloping Backfill
Authored By: NCS GeoResources, LLC
Report Date: October 2011

Abstract
This example problem presents a detailed solution for a typical cast-in-place (CIP) wall used by the Arizona Department of Transportation (ADOT). A sloping backfill configuration is assumed. The solution uses ADOT policies to demonstrate the application of LRFD principles in analyzing the external stability limit states that include strength limit states (bearing resistance, sliding, and limiting eccentricity) and service limit state (settlement). Each step is referenced to applicable AASHTO and ADOT policies. The example problem was developed by NCS GeoResources, LLC, under a task order of an on-call contract with ADOT Materials Group. ADOT Bridge Group reviewed the computations for conformance with its standards and used the approach to develop the bearing pressures for strength and service limit states for the ADOT SD 7.01 walls.
