LOADING ON SIMULATED BURIED STRUCTURES AT HIGH INCIDENT OVERPRESSURES
Abstract
This project was conducted to study the factors affecting transmission of air-induced ground pressures and loadings produced on buried structures by such pressures. The field test program involved 68 devices (drums) composed of rigid cylinders with deformable-diaphragm ends. Five diaphragm thicknesses were used to simulate structures of different flexibilities. The drums were buried at depths ranging from 0 to 20 ft at three different locations. Static measurements made on the diaphragms before and after the test consisted of strain-gage readings and permanent-deflection measurements. Transient strain measurements also were made on some of the diaphragms. A laboratory program was conducted to calibrate the field test devices. The results indicated that there was a considerable decrease with depth of the air-induced ground-transmitted pressure, as indicated by pressures on similar diaphragms at different depths. This amounted to 70% in 20 ft. (Author)
