Analysis of Mechanical Response for Subgrade of Tramcar with Monolithic Track-Bed

Abstract

Based on the differences between the subgrade of tramcar with monolithic track-bed and the existing subgrade of railway, anew three-dimensional nonlinear finite element model is established in this paper. And then,the numerical analyses are conducted by considering weight load of track structure. The characteristics of mechanical response in the subgrade of tramcar with monolithic track-bed are found by finite analysis, which offers a reference for the future engineering, in terms of the design concept, design basis and theoretical support as well as the basis for decision making.
