CRTS1哈尔滨地铁轨道结构温度效应分析

摘要：哈尔滨作为中国寒冷城市的代表，它所体现的地铁轨道方面面临的施工以及其他方面的难点可以作为研究对象进行研究，哈尔滨具有季节性动图的地质条件，而且整年温差较大，冬季最低温可达到-38度，夏季高温也达到37度，所以以温度作为哈尔滨轨道结构的研究对象比较具有研究性。近几年来哈尔滨地铁的发展也在如火如荼的进行，所以研究温度对轨道结构的影响十分有用。目前在哈达客运专线上应用的CRTS1型轨道板具有较高的抗寒性质，目前我国轨道系统的发展中，无砟轨道也在逐步代替传统的有砟轨道，无砟轨道的使用性能，包括了提供速度和稳定性以及安全性方面的显著优点，代表着无砟轨道将越来越多的被利用和普遍。本文就旨在使用ANSYS有限元分析软件研究哈尔滨地区使用的CRTS1型轨道在高寒和高热条件下内部变形以及内力变化方面的影响。通过对其经行研究而使得CRTS1型跪倒在设计和使用的时候更加有效的被利用。69519

Analysis of temperature effect on track structure of Harbin Metro

Abstract:The representative of China’s cold city is Harbin , it reflects the construction difficulty facing the subway and other aspects can be used as the research object, Harbin has the geological conditions of the seasonal dynamic map, Harbin's year-round temperature difference, can reach -41.4 low temperature in winter, summer temperatures reached 51.9 degrees, so as to temperature the research object of Harbin rail structure compared with the research. In recent years the development of Harbin subway is also in like a raging fire, so to study the effect of temperature on the track structure is very useful. CRTS1 type rail board is currently used in the Hada PDL has high cold resistance The nature, current development of track system in China, the ballast less track has gradually replaced the traditional ballasted track and ballastless track performance, which offers significant advantages of speed and stability and security, on behalf of the ballastless track will be used more and more widespread. And this paper is aimed at the impact of internal CRTS1 type track use of ANSYS finite element analysis software in Harbin area in the alpine and deformation under high heat and force change. Based on the research by the line makes type CRTS1 fell when the design and use of more effective use.
