ANALYTICAL PARAMETRIC STUDY OF A TIED-BACK SYSTEM FOR REINFORCING DISTRESSED BRIDGE ABUTMENTS

Many bridge abutments in South Dakota have experienced significant lateral movements. One of the proposed remedial methods for repairing this distress condition is a tied-back reinforcement system that consists of regularly spaced tie-rods with deadman provided at their ends. Anchorage by means of cylindrical drilled-in concrete pile deadman have typically been employed. A computer program, which includes a design method based on the limiting equilibrium approach and an analysis method using the generalized plane strain finite element method for a detailed study of tie-back reinforcement system, was developed by the author. This parametric study is intended to identify qualitatively the relative significance of several design parameters that typically govern the behavior of the tied-back abutment reinforcing system. To generalize the results of this parametric study however, it is necessary to include other geometric and material configurations than those considered in this study.
