Abstract: MATLAB language is extensively used in engineering area. As well, simulation method based on MATLAB is proposed and designed to detect the dam defects. The paper introduced the theoretical foundation for numerical simulation of ground penetrating radar(GPR) and established the mathematical model. Then, simulations in kinds of cases were carried out. The results showed that it was valid and feasible to forecast the detection results by GPR for dams.

摘要： 利用MATLAB语言进行探地雷达堤坝隐患探测数值模拟方法的研究。首先，着重介绍了探地雷达数值模拟的理论基础，然后建立了进行探地雷达二维计算模拟的物理模型，最后利用各种介质参数条件下的模型进行了数值仿真，结果表明方法是有效的，可以对探地雷达进行堤坝检测的效果进行预测。
