摘要
在分析地质雷达技术的工作原理、测线布置、参数设置方法的基础上,结合重庆礼让隧道工程实例,对测量数据进行了处理和分析,得出相应的地质雷达分析图,分析了超前地质预报中的几种典型不良地质现象。同时使用地质雷达进行了隧道衬砌质量检测,结合工程实测图,对衬砌的混凝土厚度及缺陷、钢筋及钢支撑数量进行了检测。研究表明:将地质雷达应用于隧道超前地质预报和衬砌质量检测的结果较准确,可有效提高隧道施工进度,保证施工安全,确保施工质量,对于同类工程施工也有一定的借鉴价值。
In recent years, the ground penetrating radar （GPR） is widely used in the engineering construction field. Based on analyzing the working principle, measurement lines layout method and param- eters setting method of GPR, combing with the actual engineering example of the Lirang tunnel in Chongqing city, the measurement data of GPR is analyzed and processed effectively, the related GPR anal- ysis maps is obtained, and the several classical adverse geological phenomenons in the process of advances prediction by using GPR is also discussed in detail. Besides that, the lining quality of tunnel is tested by using GPR,combing with the engineering measured maps,the thickness and defects of the concrete, steel bar and steel support numbers of lining are tested. The study results show that the reliability of the ad- vanced geological prediction results and lining quality testing results are good, it is good to improve the tunnel construction schedule, ensure construction safety and construction quality, therefore, the application results of GPR in this paper can provide some reference for the similar engineering construction.
