Static and Dynamic Bearing Tests on a Strip Footing in Saturated Sand

摘要

The report describes the static and dynamic loading of a 12-inch-wide by 18-inch-deep by 6-foot-long rigid footing, representing the strip footing of a subsurface shelter. Boundary conditions simulated those of a torsionally restrained footing of a flexible arch structure with simulated overburden of 20 feet at one side of the footing. Saturated and partially saturated sand was the test soil. Several soil void ratios were employed, and the effect on the relationship between load and displacement of the footing caused by soil saturation at void ratios higher than the critical void ratio was desmonstrated.
