| 摘 要： | 随着国内基础设施的建设,隧道工程的投资也在不断增加。隧道工程内有诸多的隐蔽工程,其质量的控制与检查过程存在许多困难。地质雷达检测法作为一种较先进的检测手段,具有快速、高效、无损等优点,在隧道工程施工过程中得到广泛应用。以遂资眉高速公路万家沟隧道的质量检测项目为依托,针对检测过程中出现的钢架数量与实际不符等问题,提出钢架数据处理过程中的分段识别,检测结果与实际验证的准确率达97.2%。

| Abstract: | With the development of domestic infrastructures,tunnel project investments have been increasing. Tunnel engineering has many hidden works and many difficulties remain in quality control.Ground penetrating radar detection,as a kind of advanced detection method,has been widely used during tunnel construction due to fast speed, effectiveness, non destructiveness it offers. Based on the preliminary support quality testing of Wan Jiagou tunnel,located in Sui Zi Mei expressway,this paper addresses the problem that the number of steel frame detected are inconsistent with the actual one and proposes sectional recognition applied to steel frame data processing. The detection results reach 97. 2%accuracy against actual verification. |
