地质雷达技术在隧道健康诊断中的应用
|
摘要
为了诊断运营中隧道病害的程度,需要对隧道衬砌作出系统评价。本文结合工程实际,阐述了采用地质雷达对隧道衬砌进行检测的原理及方法,采取提高检测效果的方法和技术措施,并通过典型雷达图像分析了衬砌结构完整性和衬砌厚度识别判定特征,取得了较好的检测效果,为隧道整体健康诊断提供依据。
In order to diagnose the disease degree of operation tunnels, it is necessary to make a systematic estimation of lining.The fundamental principles and the method for application of geological radar is explained in lining detection through series of methods and measures applying ground probing radar to a tunnel engineering.Based on analyzing different condition representation on radar profiles with some typical radar images,the better detection effect was got,which could give a basis for Diagnosis.
