双曲线模型在高速铁路路基沉降预测中的应用研究

Application of Hyperbolic Model in Subsidence Monitoring for High Speed Railway

目前我国正在大规模建设世界一流的高速客运专线,高速铁路沉降监测是高速铁路建设工程中的重中之重,因此,有效处理沉降监测数据以及沉降预报问题尤为突出。首先介绍了双曲线模型原理,其次通过实例观测沉降数据,建立了相应的双曲线预报模型,最后通过Matlab编程进行数据分析,并与实测数据进行对比。结果表明,沉降预报曲线与实测数据趋势基本一致,达到了预期效果。

Currently, world first class high - speed passenger dedicated lines are under construction in large scale in China, and the subsidence monitoring for the high speed railways under construction is the priority among priorities. Therefore, to effectively process data of subsidence monitoring and to forecast the subsidence are quite crucial. In this study, the Hyperbolic Model is introduced firstly. Then, secondly, a hyperbolic forecast model is built out of the previous data obtained from practical subsidence monitoring. In the end, a program is developed by Matlab to analyze the data, and as a result, the forecast curve can match the trend of measttred data. So it shows the feasibility of the Hyperbolic Model applied in subsidence forecast, and it can refer to other similar projects.
