STUDY OF THE COLLAPSE OF SMALL SOIL-SURROUNDED TUBES

Abstract

A program of experimental and theoretical work on the problem of failure of structural tubes surrounded by a thin layer of soil loaded by uniform radial outside pressures is described. The properties and the thickness of the soil layer were varied, and the failure pressure of the tube, as well as the deformations of the tube before and after failure, was observed. Theories based on idealized models of the soil-structure interaction were developed. The experimental results were then correlated with these theories to determine which, if any, of the theories explained the behavior of the samples. In addition to this work, a new testing apparatus was designed and built, in preparation for similar tests with the tube buried under a plane soil surface.
