摘要: 结合已有检测数据,分析总结隧道结构主要病害类型与分布特征,并将隧道结构病害分为表观病害、结构内部病害和结构背后病害3大类。针对不同类型病害的快速检测需求,系统梳理国内外快速检测技术和检测装备的现状,得出如下结论: 1)表观病害检测技术与装备近些年发展迅速,特别是机器视觉、激光扫描技术的结合显著提升了检测效率与精度,裂缝检测精度可达0.1 mm; 2)隧道内部和背后病害的非接触快速检测受硬件技术限制,仍以传统的检测方法为主,但近些年相控阵雷达、超声以及声振检测技术已成为研究热点,为衬砌内部和背后病害的快速检测提供了新方向; 3)多传感器融合技术在国内外快速检测装备中的应用进一步提升了检测能力,相机、三维激光扫描仪、红外热成像仪及雷达在快速检测中展现出显著优势。针对隧道检测的多学科交叉特性,未来研究应重点突破隧道结构内部和背后病害的快速检测技术,推动表里一体的多功能快速综合检测车的研发与应用,进一步发展病害全自动智能化精准识别与边检边报以大幅提升隧道检测的效率与精度。

Abstract: Based on inspection data, the authors analyze and summarize the main types and distribution characteristics of tunnel structural defects. These defects are classified into three types: surface defects, internal defects, and defects behind the structure. To address the need for rapid detection of different defect types, the current state of rapid detection technologies and equipment, both domestically and internationally, is systematically reviewed. The research reveals that surface defect detection technologies and equipment have developed rapidly in recent years. Notably, the integration of machine vision and laser scanning technologies have significantly improved detection efficiency and accuracy, achieving crack detection precision of up to 0.1 mm. However, the noncontact rapid detection of internal and behind-the-structure defects remains constrained by hardware limitations, with traditional detection remaining dominant. Nevertheless, phased array radar, ultrasonic, and acoustic vibration detection technologies have become research hotspots in recent years, offering promising directions for detecting these challenging defect types. Additionally, the application of multisensor fusion technology in rapid detection equipment has further enhanced detection capabilities. Devices such as cameras, 3D laser scanners, infrared thermal imagers, and radar demonstrate significant advantages in rapid detection. Future research in tunnel inspection should prioritize breakthroughs in rapid detection technologies for internal and behind-the-structure defects. Efforts should also focus on developing multifunctional integrated detection vehicles that can simultaneously inspect both surface and internal structures. Furthermore, progress in fully automated, intelligent systems with precise defect identification and real-time reporting will be essential to significantly improve the efficiency and accuracy of tunnel inspection.
