In Situ Testing for Lock and Dam 26 Cellular Cofferdam

Document Type: Proceeding Paper

Part of: Use of In Situ Tests in Geotechnical Engineering

Abstract:

The in situ testing consisted of split spoon and cone penetration tests, Menard and self-boring pressuremeter tests, and Marchetti dilatometer tests. The testing program proved to be challenging because of the presence of gravels in the fill, the influence of arching caused by the soil structure interaction process, and density differences between the center and edges of the fills. Soil parameters from the in situ tests were in reasonable agreement with those obtained in laboratory tests in most cases. In situ lateral stresses were overpredicted, with those from the Marchetti dilatometer closest to the values expected. The results also show that the in situ test results are sensitive to stress changes caused by the soil-structure interaction process.
