摘　　要：铁路路基病害的有效监测对于铁路系统安全运维具有重要意义,然而铁路路基病害发生的渐变性和不确定性导致传统人工监测方式精度低、效果差。针对该问题,以包神铁路神瓷线高挡墙护坡监测为例,基于北斗GNSS和SMOS建立铁路路基病害在线监测预警系统,该系统具有数据自动采集、智能分析、实时传输等功能,在此基础上,提出一种联合使用小波变换和支撑向量机的组合模型实现对变形趋势的高精度预测,从而帮助用户掌握路基病害当前状态和变化趋势,了解路基病害的演化过程,从而实现在高挡墙护坡稳定性异常的早期及时发现和预测,具有较高的应用前景。Effective monitoring of railway roadbed diseases is of great significance for the safe operation and maintenance of railway systems.However,the gradient and uncertainty of railway roadbed diseases lead to low accuracy and poor effectiveness of traditional manual monitoring methods.In response to the issue of improvement,taking the monitoring of high retaining walls and slope protection on the Shenci Line of the Baoshen Railway as an example,an online monitoring and warning system for railway roadbed diseases is established based on Beidou GNSS and SMOS.The system has functions such as automatic data collection,intelligent analysis,real-time transmission,and early warning.This system can help users grasp the current status and changing trends of roadbed diseases.This system can help users understand the evolution process of roadbed diseases,thereby enabling early detection and prediction of abnormal stability of high retaining walls and slope protection.This system has high application prospects.
