重载铁路路基基床动应力分布特征研究
Study on Subgrade Dynamic Stress Distribution of Heavy Haul Railway
摘要
Abstract
With the promotion of national railway transportation policy about separation of passenger and freight, heavy haul railway as an internationally recognized advanced freight transportation is gradually accepted by Chinese railway builders and put into practice. In China, the design specification for heavy haul railway subgrade still remains incomplete and the subgrade structure differs much with the world advanced heavy haul railways. With reference to the common method to treat car load, ANSYS software is used for the finite element analogue ( FEA) of the subgrade structure of the heavy haul railway and the measured dynamic stress data are compared to identify the subgrade dynamic stress distribution patterns. This paper also proposes suggestions for the improvement and optimization of current subgrade bed design and evaluates the adaptability of 30 t heavy haul train on the subgrade of Shanxi-Henan-Shandong railway.关键词
