註釋This study of the Bonneville Navigation Lock temporary tieback wall was performed to analytically confirm the design of the wall and to predict its performance during construction operations. The method chosen to do this involves finite element (FE) soil-structure interaction analysis. The method of modeling the wall-soil relationship provides a detailed and accurate representation of the system and its response to various loadings. The objectives of the study were met through both the development and analysis of a finite element model with the program SOILSTRUCT and assessment of the measured field performance of the wall. The analysis and instrumentation results showed that the wall section studied deflected less than the 0.1-ft limit set by design criteria. In addition, the incremental analysis allowed prediction of wall performance during construction. The analysis results were used in conjunction with the instrumentation results to verify both the FE model and the instrumentation. The results produced by the FE analyses are wall deflection, bending moment, earth pressure distribution, anchor loads, ground surface movement, and soil stresses. (sdw).
