在桥梁运营时,由于频繁承载,甚至超载;再加上自然界乃至自然灾害的侵袭以及交通事故等人为事端的侵袭,会造成桥梁损伤和局部破坏。为了保证既有桥的安全运营和尽可能延长其安全使用年限,应对既有桥进行检测,而且应定期进行全面检查。所谓全面检查就是对桥梁的引道、周边环境、地基下部结构、上部结构、桥面(包括桥面铺装层、伸缩缝、人行道、栏杆、防撞设施、排水设施、照明及防雷设施)、支座等作全面查看、量测。提出了全面检查应检的部位,并探讨检测桥梁的新方法。
In the bridge operation, due to frequent carrying, or even overload; coupled with natural and even natural disasters and traffic accidents and other man-made attacks on the incident, will cause damage to the bridge and local damage. In order to ensure the safe operation of the existing bridge and extend its safe service life as much as possible, the existing bridge should be tested and the inspection should be carried out on a regular basis. The so-called comprehensive inspection of the bridge approach, the surrounding environment, the foundation of the substructure, the superstructure, the bridge deck (including the deck pavement, expansion joints, sidewalks, railings, collision avoidance facilities, drainage facilities, lighting and lightning protection facilities) , Bearings for a comprehensive view, measurement. Proposed a comprehensive inspection of the site should be inspected, and explore new methods of testing bridges.
