Penetration Performance of Steel Cylinders in Sand Foundations

Abstract

In order to study the effect of wall thickness on the penetration process of steel cylinders, we carried out physical tests and numerical simulations of the penetration process of steel cylinders with different wall thicknesses in sandy soil foundations, focusing on analyzing the penetration force and soil uplift during the penetration process of steel cylinders. The results show that the coupled Eulerian-Lagrangian (CEL) approach can be used to simulate the penetration process of steel cylinders. During the penetration of steel cylinders with different wall thicknesses, the relationship between the penetration force and penetration depth can be approximated by a quadratic function. The larger the wall thickness is, the larger the plug volume inside the steel cylinder during penetration. The research results can provide support for the design and construction of steel cylinders.
