摘要
从大型桥梁结构监测的要求出发,针对传统监测数据在现行监测过程中存在显示效果不明显、反馈不及时和非全自动监测报警等缺点,通过三维GIS技术建立桥梁结构监测系统,使其具有实时性、反馈性、智能性等,有力地保证了桥梁监测数据的直观表达。详细探讨了三维GIS应用于大型桥梁监测的关键技术,以武汉二七长江大桥为原型开展对具体桥梁的应用研究。结果表明,三维GIS应用于桥梁监测的技术方案能够有效地克服现有方法的缺陷,提高了桥梁监测中数据反馈、展现的能力,对相关桥梁监测的新思路具有一定的借鉴意义。
From the large bridge structural monitoring requirements,a bridge structural monitoring 3-dimension GIS platform is established,which can feed back information directly and timely,to ensure quality control during the operation of the bridge and make up the deficiencies of existing visualization means and inefficiency of data feedback.The principles and methods of how to build a health monitoring system with GIS for large bridge are discussed in detail in this paper.And then,the bridge structural monitoring 3D GIS platform for Erqi Yangtze River Bridge in Wuhan is set as an example to be studied.The result indicates that the platform based on GIS can meet the need of quality control managements in bridge health monitoring completely and the speed of data processing and visualization is increased substantially.
