瞬态瑞雷波法和地质雷达法路基结构检测对比

摘要

T ransient Rayleigh W ave method and Ground Penetrating Radar method are conventional geophysical exploration methods. During the testing of compaction at the deep location of subgrade filling,a single method shows multi-solution. T his paper based on the Ganzhou -Longyan railway construction,and tested the subgrade quality with above methods. By appling these two methods on special subgrade structure( Karst subgrade) ,a large number of field tests were obtained. An analysis between those applications have been done. Based on the test results,the advantages and applicability were compared to clarify that a combination way of two common geophysical detection methods is an important developing direction for the subgrade nondestructive testing.%瞬态瑞雷波法和地质雷达法属于常规物探方法，用于路基填筑体深部密实情况检测时，单一方法的检测结果具有多解性特征。文章依托赣龙复线铁路工程建设，选取特殊的路基结构(岩溶路基)，应用瞬态瑞雷波法和地质雷达法进行路基质量检测。根据检测结果对比分析2种方法各自的优点和适用性，阐明将2种方法结合起来的综合物探法将是路基质量无损检测的发展方向。
