铁路路基病害类型、机理及检测与整治技术

TYPES AND MECHANISMS OF ROADBED DEFECTS IN EXISTING RAILWAYS AND THEIR DETECTION AS WELL AS TREATMENT

针对既有铁路的特点,分析了常见铁路路基病害的类型、机理;提出路基病害的检测应运用现代化检测工具,采用原位和区段测试相结合的方法;针对路基病害整治技术的复杂多样,整治具体路基病害的困难性,指出了铁路路基病害智能管理系统能较好地解决此问题。

Based on the feature of the existing railway,the authors analyze types and mechanisms of roadbed defects. The authors then present a new method in detection of roadbed defects, which combines the spot detection and section verification using modern equipment. Considering complexity of measures for treatment of roadbed defection as well as difficulties in their implementation, the authors conclude that an intelligent management system of railway roadbed defects will be a very effective tool in assessing railroad roadbed defects and selecting appropriate measures for treatment.
