铁路路基翻浆冒泥的机理及影响因素

Mechanism and Influencing Factors of Mud Pouring from Railway Subgrade

随着现代社会经济的进步发展,我国的交通网络也越来越完善,铁路建设是我国当前重要的交通建设项目,其建设质量直接关系到人们的生命安全以及区域经济交流水平。在其建设过程中,路基施工作为重要的基础工程,需要施工单位在充分考察施工现场环境的基础上进行施工,但是就当前铁路运行的情况来看,路基翻浆冒泥的现象时有发生,主要是因为铁路在运行过程中不仅会承受铁路轨道的重量及机车车辆的动力荷载,还会长时间受到水流、风沙、雨雪、严寒、高温等的侵袭和各种不良地质条件及人为因素的影响,导致路基结构发生变化,加剧翻浆冒泥病害的发生,严重威胁着铁路运行安全。基于此,本文就铁路路基翻浆冒泥的机理及其影响因素进行了分析。

With the development of modern society and economy,China's traffic network is becoming more and more perfect.Railway construction is an important traffic construction project in China.Its construction quality is directly related to people's life safety and regional economic exchange level.In the process of its construction,as an important foundation project,subgrade construction needs to be carried out by the construction company on the basis of full investigation of the construction site environment.However,in terms of the current railway operation,the phenomenon of subgrade mud pouring occurs from time to time,mainly because the railway will not only bear the weight of the railway track and the dynamic load of the locomotive and vehicle,but also be long Due to the invasion of water flow,sand,rain and snow,severe cold and high temperature,as well as the influence of various adverse geological conditions and human factors,the subgrade structure has changed,which aggravates the occurrence of mud pouring disease and seriously threatens the safety of railway operation.Based on this,this paper analyzes the mechanism and influencing factors of mud pouring from railway subgrade.
