Using the backfill placement method of analysis, the authors were able to use a limited amount of data on soil properties and limited instrumentation readings to estimate lock performance from initial construction through major flood events, including siltation. Results of the complete soil-structure-foundation interaction analyses for four operational load cases were critical in interpreting instrumentation measurements. A distinction was made between soil-structure interaction of the compacted sand backfill and the stem walls and the interaction of the compacted sand backfill and the culvert walls. This investigation considered the characterization of the range in magnitudes and distributions of horizontal earth pressure coefficient, Kh, and vertical earth pressure coefficient, Kv, along the stem and culvert walls for each load case. Expressing the effective normal pressure and vertical shear stress along lock walls, in relation to earth pressure coefficients, allowed for the precise recovery of both normal and shear stresses for use in simplified design tools.
