Abstract

Experimental data obtained from a series of static arching tests run on vertically oriented rigid-base cylindrical structures buried in a partially saturated low plasticity soil are presented. The experimental results are compared to an available analytical approach. The axial stiffness of the structure, the confined tangent modulus (stiffness) of the soil, and the applied surface overpressure were varied. The most important measurement in this experimental study was the total load carried by the structure for different values of structural stiffness and soil stiffness. The index properties, as well as the shear strength and angle of internal friction for the soil were determined. A moisture content of 10 percent was used for all test samples. It was found that a static compaction consistently reproduced uniform and homogeneous samples. Relatively good agreement was obtained between experimental data and the theoretical computations for the active arching case. Poor agreement was obtained between theory and experiment for the passive arching case.
