| Abstract: | 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. |
