摘要
根据《公路工程竣(交)工验收办法实施细则》对隧道的要求,介绍了地质雷达用于公路隧道交工验收的检测方法,包括仪器设备选择、检测测线布置、混凝土相对介电常数标定等内容,分析了二次衬砌厚度不足、二次衬砌后空洞、二次衬砌不密实、防水板卷入二次衬砌等常见病害缺陷,指出了实施细则与检测方法的不足并提出相应的改进措施。
According to the Detailed Rules for Implementation of Acceptance Measures for Completion(Delivery) of Highway Projects, this article introduces the detection method of ground penetrating radar for the handover and acceptance of highway tunnel, including the selection of instruments and equipment, the layout of detection lines, the calibration of the relative dielectric constant of concrete, etc., and analyzes the insufficient thickness of the secondary lining, the cavity after the secondary lining, the non compactness of the secondary lining,the waterproof board involved in the secondary lining and other common diseases and defects, points out the shortcomings of the implementation rules and detection methods, and puts forward the corresponding improvement measures, so as to provide reference for similar work.
