摘要
衬砌背后空洞是铁路隧道衬砌质量缺陷的常见种类之一,对铁路隧道施工及运营的安全有较大的影响。地质雷达法作为一种无损检测手段,以其高分辨率、高精度及效率较高而得到较广泛的应用。该文通过对某铁路隧道衬砌质量检测中,遇到的各种衬砌质量缺陷地质雷达波形图进行解译及分析,总结出隧道衬砌空洞缺陷的几种典型地质雷达波形特征,并对其产生的原因进行了分析,为以后隧道衬砌空洞的检测及治理提供了借鉴。
The lining void behind railway tunnel is a common form of quality defects in railway tunnel lining. It has great in fluence on the safety of railway tunnel construction and operation. As a nondestructive testing method, the geological radar method has been widely used because of its high resolution, accuracy and efficiency. According to the interpretation and analysis of the geological radar wave-forms of various lining quality defects encountered in the quality inspections of a railway tunnel, several typical geological radar wave-forms characteristics of tunnel lining voids are summarized. And the causes of its occurrence are analyzed. It provides reference for the detection and treatment of tunnel lining void in the future.
