摘要
针对道路桥梁传统测量方法检测速度慢,准确度低等问题,文中研究探讨了基于无损检测的道路桥梁工程测量技术。无损检测可以在不损伤或不影响道桥结构的条件下,完成对被测对象的测量。通过超声波对桥梁的无损检测,结果说明,无损检测技术能够准确、快速地判断桥梁的缝隙位置和受损程度,验证了无损检测在道路桥梁工程测量上的可行性,为工作人员及时处理提供了重要支持。随着道路桥梁建设规模的增多以及使用年限增加,无损检测技术在道路桥梁验收和测量内部结构损伤等方面将更加具有研究价值。
Aiming at the problems of slow detection speed and low accuracy of traditional measurement methods for road and bridge,the road and bridge engineering measurement technology is studied and discussed based on non-destructive testing.Non-destructive testing can complete the measurement of the object under the condition of no damage or no influence on the structure of the road and bridge.The non-destructive testing results of the bridge by ultrasonic show that the non-destructive testing technology can accurately and quickly judge the position of the bridge gap and the degree of damage,and verify the feasibility of non-destructive testing in road and bridge engineering survey.It provides important support for the timely handling of staff.With the increase of road and bridge construction scale and service life,non-destructive testing technology will have more research value in road and bridge acceptance and internal structure damage measurement.
