Research on Data Model of Railway Rainfall Steel Structure Health Monitoring Based on BIM Model

结构健康监测是保障重大工程结构安全的重要技术,针对铁路站台雨棚钢结构监测过程中出现的站台模型和监测信息数据庞大的问题,提出一种扩展的BIM模型,即在现有的BIM模型信息中以数据信息的唯一标识作为依据,扩展所需的动态监测数据信息,将各类检测数据进行有效整合。首先对系统总体架构进行设计,设计面向钢结构健康监测信息的BIM模型,对系统总体架构合计,再根据扩展的BIM模型和模型数据,应用扩展的BIM模型系统设计,开发了基于BIM模型的监测系统,实现了铁路站台雨棚的有效监测。

Structural health monitoring is an important technology to ensure the safety of major engineering structures.Aiming at the problems of the platform model and huge monitoring information data encountered in the steel structure monitoring of railway platform canopy,an extended BIM(Building Information Modeling)model is proposed.Based on the unique identification of the data information in the existing BIM model information,the required dynamic monitoring data information is expanded,and various types of detection data are effectively integrated.First,the overall architecture of the system is designed,a BIM model for steel structure health monitoring information is established,and the overall system architecture is totaled.Then,a BIM-model-based monitoring system is developed by means of extended BIM model system design on the basis of the extended BIM model and the model data.The effective monitoring of the railway platform canopy is thus realized.
