摘要
桥墩基础是桥梁结构重要的承重结构,水下桥墩基础受水流冲刷作用存在损坏的风险,对水下桥墩基础进行巡检十分必要.为此,提出了利用水下三维声纳和多波束测深系统在水下桥墩巡检中联合应用的方法,将三维声纳应用于水下桥墩基础本身的检测,多波束测深系统应用于基础周围河床的测量,能充分发挥两种设备的优势,得到水下桥墩基础的三维影像和水深数据,并利用位姿信息对两类数据进行精确匹配和融合,对结果进行一体化三维影像展示.利用浙江某跨河大桥水下桥墩基础检测的实际案例验证了方法的有效性,此方法可广泛推广于水下桥墩巡检工程中,为桥梁的安全运营提供基础数据支撑.
Abstract
Bridge pier foundation is an important load-bearing structure of bridge structures,which is at risk of being damaged by current scour,so it is necessary to inspect underwater pier foundation.This paper proposes a method of the joint application of three-dimensional sonar and multibeam echosounder in underwater bridge pier patrol inspection.The three-dimensional sonar is applied to the detection of the underwater bridge pier foundation and the multibeam echosounder is applied to the measurement of the riverbed around the foundation,which can fully utilize the advantages of the two devices to obtain three-dimensional images and water depth data,and accurately match and merge the two types of data by position and attitude information,and display the results in an integrated three-dimensional image.The effectiveness of the method is verified by an actual case of underwater pier foundation inspection of a river crossing bridge in Zhejiang Province.This method can be widely applied to underwater pier inspection projects and provide basic data support for the safe operation of bridges.
