Investigation of Soil-Structure Interaction: Flexible Culvert Pipes

摘要

Triaxial and 'trapdoor' tests were conducted on a sand to determine its stress-strain properties. Results of tests by Waterways Experiment Station and others are included in the report. Measured stresses compared closely to computed stresses. Computed deflections were many times greater than measured deflections for an undetermined reason. The report includes a print out of a finite element computer program developed by Brown of California and modified by the researchers to take into account nonlinear soil properties. Using the program, preliminary calculations were made for one set of conditions to illustrate the nature of results obtainable. (BPR abstract)
