Abstract

The U.S. Army Corps of Engineers (Louisville District) conducted a number of full-scale tests to determine the behavior of continuous steel sheet pile flood walls when subjected to hydrostatic loads simulating actual flood conditions. Among these tests, Test Series III (sheet piling with concrete jacket) was conducted at the Tell City site in Indiana. The results of these full-scale load tests provide valuable data that could help verify geotechnical design procedures. In addition, numerical analyses simulating these tests could be useful in interpreting the foundation and structure behavior and in predicting the performance of similar I-wall-type levee systems subjected to flood loading conditions. The full-scale load test was conducted on a portion (42 feet long) of the completed flood wall. Three-dimensional (3D) numerical finite difference (FLAC 3D) models for an I-wall that simulate full-scale load test conditions were developed to compute wall deflections and compare with the measured deflections from the full-scale test. This approach was used because it was recognized that using 2D analyses for the 3D load test conditions did not accurately simulate actual conditions. The analyses performed in this study provided quantitative estimates of wall displacements that reasonably simulate the 3D effects of the load tests on the levee wall.

Three Dimensional Soil-Structure-Interaction Analysis of a Flood Wall Under Full-Scale Load Test

Chicago, Illinois

The U.S. Army Corps of Engineers (Louisville District) conducted a number of full-scale tests to determine the behavior of continuous steel sheet pile flood walls when subjected to hydrostatic loads simulating actual flood conditions.

In addition, numerical analyses simulating these tests could be useful in interpreting the foundation and structure behavior and in predicting the performance of similar I-wall-type levee systems subjected to flood loading conditions. The full-scale load test was conducted on a portion (42 feet long) of the completed flood wall. Three-dimensional (3D) numerical finite difference (FLAC 3D) models for an I-wall that simulate full-scale load test conditions were developed to compute wall deflections and compare with the measured deflections from the full-scale test. This approach was used because it was recognized that using 2D analyses for the 3D load test conditions did not accurately simulate actual conditions.
