Final Technical Report

The purpose of this proposed project is to verify the safety of bridge foundations designed with an improved/modified lateral spreading design procedure using nonlinear 3D finite element models. The current design procedures used for liquefaction-induced lateral spreading are often overly conservative due to the simplifying assumptions involved in their use. A modified design procedure (Martin et al., 2002; Zha, 2004; Boulanger et al., 2006; Ashford et al., 2011) that is part of the focus of this proposed work has been developed as a means to more appropriately consider the relevant aspects of the laterally-spreading bridge-foundation-soil system. This procedure has been shown to be effective in its intended purpose of reducing some of the excessive conservatism associated with more simplified design approaches, however, there has only been limited testing and analysis to verify and benchmark the relative safety of the resulting design solutions for a wide range of bridges, foundations, and soil conditions.
