Study on Tunnel Concrete Structure Theoretical Model and Its Characteristics of Radar Reflection

摘要: 理论模型的研究有助于处理实际中的复杂问题，应用数学的方法研究发生在这个模型里的物理现象的基本规律，通过计算机计算由这个模型产生的雷达响应，分析其雷达波反射特征来达到识别层位、解决实际问题的目的。所以为提高对雷达图像的处理和解释能力，本文通过对隧道混凝土结构的雷达无损检测基本理论进行研究，建立了隧道混凝土结构的理论模型，实现了其雷达信号的正演合成。

Abstract: Study on theory model helps us to process the complicated problem in practice, the basic law of the physical phenomenon in the model is studied by using the mathematical technique, the Radar response of the model is calculated with the computer, the reflection character of the Radar wave is analyzed to identify the geological horizon and solve the practical problem. So, in order to improve the ability in processing and interpreting the GPR data, The author has learnt a great deal of basic principles about GPR, and studied the theory of the non-destructive examination to tunnel lining, and then structured the tunnel concrete structure model and attained the Synthetic GPR record.
