Abstract : Lock and Dam No. 1 on the Red River Waterway has experienced a serious siltation problem since its completion in 1983. This technical report summarizes the results of a soil-structure interaction analysis of a potentially permanent, low-maintenance solution to this problem, i.e., construction of a reinforced soil retaining wall adjacent to the riverside lock wall. The principal objective of this research was to assess potential lock performance after construction of a reinforced soil retaining wall adjacent to the riverside lock wall. Due to the nature of the problem, the conventional analysis techniques, which are based upon the equations of equilibrium and used in the design of reinforced soil retaining walls, did not provide sufficient information to satisfactorily evaluate performance of this structure with regard to its interaction with the lock and the surrounding foundation soil strate. The general purpose, nonlinear, incremental construction, finite element computer program, SOILSTRUCT was used to analyze the complex soil-structure interaction by simulating the staged construction.
