Experimental Study of Arching Stresses on Buried Vertical Cylingders

摘要

This report describes the first phase of a sustained research effort to study arching stresses on buried structures caused by modulus mismatch between structure and surrounding medium. A series of duplicate tests was performed on cylindrical and disc structures specially designed to separate arching stresses from side-wall frictional effects. All tests were static, using 20-30 dry Ottawa sand at three different densities. The applied over-pressure and the geometric configuration of the buried structures were varied to facilitate a study of the influence of these parameters on soil-structure interaction. (Author)
