铁路路基双块式无砟轨道裂缝控制策略

Control Strategy for Cracks in Railway Subgrade with Double Block Blast Track

相关研究显示,无砟轨道建设及运行过程中存在裂缝问题,尤其是钢筋混凝土结构。受环境因素、梯度荷载、轴向荷载及列车荷载的影响,高速铁路无砟轨道混凝土结构会出现裂缝、断裂及扩展,严重影响无砟轨道的使用寿命和安全。因此,本文分析了铁路路基双块式无砟轨道裂缝控制策略。

Related research shows that cracks occure during the construction and operation of ballastless tracks.In the course of work,crack problem appeare in reinforced concrete structure.Due to environmental factors,gradient loads,axial loads and train loads,the concrete structure of ballastless track of high-speed railway have cracks,fractures and extensions,which seriously affect the service life and safety of ballastless track.Therefore,the control strategy of railway roadbed double-block ballastless track crack was analyzed.
