摘要
针对高速铁路长大桥梁无砟轨道无缝线路这一复杂体系,以国内某高速铁路建设为背景,通过对该高速铁路长大桥梁无砟轨道无缝线路的试验研究,研制了高速铁路长大桥梁无砟轨道无缝线路长期、远程和实时监测系统。利用远程监测所得到的应变,推导了伸缩附加力的计算公式。运用该方法对某高速铁路长大桥梁无砟轨道无缝线路进行了监测,试验结果验证了监测系统的可行性和有效性。
Aim to the complex system of unballasted track in CWR on long bridges of high-speed railway,based on the construction of a high-speed railway in China and by using of experimental research of this line,a long-term,remote and real-time monitoring system of unballasted CWR track on long bridges of high-speed railway was developed in this paper.Using strain obtained from the remote monitoring,the formula of calculating additional contractility was further deduced.Applying this method to monitor the unballasted track in CWR on long bridges of high-speed railway,the test results verified the feasibility and effectiveness of the monitoring system.
