摘要
如何在保持线路运营条件下,对路基性能进行综合无损检测,对其服役状态进行评估,对病害的成因机理、发展趋势作出分析和诊断,并据此开展维护修复工作,从而保证我国路基工程的良好性状,已成为我国高速铁路必须面对和亟待解决的问题。本文通过对地质雷达、瞬态面波、冲击弹性波、冲击回波、板冲击瞬态脉冲响应检测方法的研究,提出了一套适用于运营高速铁路路基基床的综合检测方法技术,并综合概括出了运营高速铁路路基基床检测与质量评价标准。
Under the conditions of keeping the line operation, how to conduct comprehensive nondestructive testing of the roadbed performance, evaluate the status of service, make the analysis and diagnosis of the disease mechanism and devel- opment trend, and accordingly to carry out maintenance and repair work to keep the good characteristics of the roadbed en- gineering, has been a burning issue waiting for solving in China＇ s high-speed railway. By studying the detection methods of the geological radar, transient surface wave, impact elastic wave, impact echo and plate impact transient pulse response, this paper proposed a set of comprehensive technologies suitable for detecting subgrade bed of high-speed railway in opera- tion and summarized the detection and quality evaluation criteria for subgrade bed of high-speed railway in operation.
