摘要
以摄影测量技术为基础的快速检测车可实现运营隧道衬砌结构病害检测的快速化,克服了传统人工检测方法的低效率、主观性强和需要交通管制等缺点。本文重点介绍了快速检测车的构成及工作性能,并通过实际工程应用验证其检测结果的准确性。最后基于隧道快速检测结果,建立了一套运营隧道结构安全监控的预测预报系统。
The rapid detection vehicle based on photogrammetry technology can realize the rapid detection of the lining structure diseases of operating tunnels,and overcome the shortcomings of traditional manual detection methods such as low efficiency,subjectivity and the need for traffic control.This paper focuses on the composition and performance of the rapid detection vehicle,and verifies the accuracy of the test results through practical engineering applications.Finally,based on the rapid detection results of tunnels,a set of prediction system for safety monitoring of operating tunnels is established.
