Experimental and theoretical results are given that provide information on the influence of soil properties on the behaviour of buried cylinders whose axes are parallel to the surface. Sand type, density, and cylinder stiffness were varied in 12 static tests on 5-in. Diameter thin metal cylinders. The stiffness of these cylinders was less than that of others in the literature for which complete information on soil properties was available. This research provide a unified method for determining deflections and the critical buckling load based on the one-dimensional confined compression modulus from a standard laboratory test. Also, a relation for arching across buried cylinders that permits computation of the thrust at the haunches is given, and an equation is proposed for estimating interface pressure distribution from measurements of strains in the cylinder. /author/.
