摘要
探地雷达检测具有简便、效率高和应用范围广的特点。在堤防工程病害检测中,以往雷达图像解释通常需要大量的试验和野外工作经验来相互验证,受各种条件的制约,使得检测工作效率下降。而利用数值模拟方法,对工程病害进行数值模拟计算,参照模拟结果进行对比解释,有助于病害判断,提高解释的准确性。本文通过对典型堤防工程病害的探地雷达数值模拟,为探地雷达图像识别提供了依据和经验。
GPR detection is a simple and convenient method, with high efficiency and wide application range.In dike engineering disease detection, previous interpretation of radar image usually needs a lot of test and field work experience to verify each other, but this method is restricted by various conditions, thus this causes the declining of detection efficiency. However, it is helpful for the judgment of the disease and the enhancement of interpretation accuracy by using numerical simulation method to simulate the engineering disease. This essay provides the basis and experience for GPR image recognition through simulating the typical dike engineering disease in GPR numerical simulation.
