1、I 公路隧道隐伏病害快速无损诊测与安全评价体系构建 摘 要 我国隧道建设起步晚、发展快，目前已成为世界上隧道分布最多的国家。由于隧道特殊的结构，运营过程中存在的诸多因素将造成隧道各类病害出现，严重威胁隧道结构安全以及交通行车安全。对隧道结构病害进行检测及安全 评价成为一项重要工作，但目前我国并没有关于隧道病害检测及评价的统一规范。基于此，本文主要从隧道病害检测方法以及安全评价方法两方面开展研究，为相关规范的编制提供技术支撑。 目前，隧道病害检测方法主要有传统法和无损检测法，本文主要关注无损检测法中的探地雷达检测法，重点研究检测中干扰信号的甄别和压制方法，不同病害的异常特征的判定方法，并初步构建
2、一套完整的无损检测体系。此外，还利用多层次模糊综合评价模型对隧道的安全状态进行定量分析，实现隧道安全等级的判定。 论共分为五章， 第一章主要介绍相关研究现状，研究内容、技术路 线和取得的创新性成果等 。第二章主要介绍探地雷达的理论基础，总结了不同类型隧道隐伏病害形式，通过实测数据和基于 时间域有限差分法的正演模拟数据介绍了隧道病害典型异常特征；构建了隧道隐伏病害无损检测体系， 使得检测过程规范化、系统化，提高了检测效率和精度。 第三章介绍了国内外常用的隧道安全评价理论，提出了隧道安全评价指标选择原则，介绍了确定评价指标权重的层次分析法，基于单层次模糊评判模型和多层次模糊综合评判模型实现了隧道安
3、全的综合判定。 第四章以济南隧道工程为例， 描述了 快速无损检测和安全评价系统 的应用情况，给出了相似 检测工作的实施模板 。 第 五 章 介绍 论文的整体研究结论及下一步工作建议。 本文研究确定的隧道隐伏病害无损探测技术体系和安全评价体系，可实现相关工作的规范化、系统化，提高隧道安全评价的准确度，为相似工程实践提供方法和技术支持。 关键字： 隧道病害 ； 无损检测 ； 安全评价 ； 多层次模糊综合评判理论 II Quick and nondestructive testing and safety evaluation system construction to hidden diseas
