摘要: 使用地质雷达法检测隧道衬砌质量业已日益得到认可,研究检测结果地质解释的准确性对于保证隧道衬砌质量具有非常重要的作用。通过现场大量工作经验的总结与理论研究,分别研究了判别二衬厚度、钢筋钢拱架分布和混凝土是否密实的方法。并以某隧道为例,分析对比检测结果与设计参数,结果表明提出的判别方法比较有效,可以用于工程实践。

Abstract: The application of the ground penetration radar (GPR) in the integrity of the tunnel liners has received more and recognitions by the tunnel practitioners. The accuracy in the GPR data interpretation is critical to the tunnel linear quality assurance.  This paper proposes the interpretation methods of the thickness of the liner, distribution of the steel frames and the density of the concrete. These methods are applied in the integrity check of a tunnel liner. The results are acceptable.
