摘　　要：在交通与水利建设中 ,隧道及涵洞施工地质条件复杂 ,工程事故多种多样。本文结合现场实测资料 ,讨论了探地雷达技术在公路隧道、引水涵洞衬砌质量及混凝土结构中钢筋铺设质量 ,进行检测方面的应用效果。实例表明 ,探地雷达技术在查明衬砌层中的缺陷与隐患的位置 ,确定混凝土衬砌层中钢筋的分布情况 ,对隧道中潜在的地质灾害进行预测 ,对工程施工质量进行评估等方面具有显著特点。As with complicated engineering geological conditions, the construction of highway tunnel and water culvert often meets various kinds of project accidents. Combined with field data, this paper has discussed the effectiveness of ground penetrating radar (GPR) in the inspection of construction quality of concrete liner of highway tunnel and water culvert and the distribution of reinforced steel bar in the concrete liner. Some examples has showed that GPR technology has remarkable characteristics in locating the defects and hidden dangerous in the liner and in investigating the distribution of reinforced steel bars in concrete liner. Prediction can be provided of the potential geological disasters in highway tunnel and water culvert, and appraise can be made with GPR data.
