AN EXPERIMENTAL INVESTIGATION OF SOIL-STRUCTURE INTERACTION IN A COHESIVE SOIL. VOLUME 2
Abstract
The study was an experimental investigation of the behavior of an idealized structure buried at various depths in a compacted cohesive soil (buckshot clay, water content = 26%). Eight static and 20 dynamic plane-wave loadings up to 310 psi were conducted. The cylindrical test devices (5 inches high and 6 inches in diameter) were oriented vertically and their stiffness relative to the soil was varied. In addition a device whose top could be extended and contracted hydraulically was buried at various depths and the relation between load and deformation changes was studied at static overpressures of 37.5 and 75 psi. At low static and dynamically applied surface pressures (PS = 37.5 psi) and a depth of burial of one structure diameter (H/B = 1), the amount of active arching depended upon the stiffness of the structure relative to that of the soil. Under these conditions, it was possible to relieve practically all the overpressure on the test structure just by decreasing its stiffness.
