                                           使用BIM软件监测桥梁安全性

In addition to facilitating the design and coordination of complex building projects, BIM is also being used by engineers to better monitor the health of vital pieces of infrastructure such as bridges. Zhigang Shen, a professor at the University of Nebraska’s School of Architectural Engineering and Construction, has developed a BIM-style software program for the express purpose of monitoring the condition of bridges.

BIM[i](Building Information Modeling建筑信息模型)不仅有助于复杂建筑的设计和协调,还能够帮助工程师做好重要基础设施(比如桥梁等)的健康监测工作。近日,内布拉斯加大学建筑与结构工程学院的沈教授开发出了一种用于监测桥梁健康状况的BIM软件程序。

 

The program creates a 3D model of real-life bridge structures in exacting detail based on data amassed via on-site inspections. According to Shen, the use of BIM enables the huge welter of data concerning the myriad components and aspects of a bridge to be incorporated into single, easy-to-access simulation, vastly expediting the monitoring process for transportation officials and inspectors.

根据现场监测积累得到的数据,这个程序可以构建出一个精确再现实体桥梁结构的3D模型。沈教授表示,一座由大量构件组成的桥梁包含着无数繁杂的数据,而BIM可以将这些计算过程简化为简单易操作的数值仿真,这大大提高了交通部门官员和监测员的工作效率。

 

“An enormous amount of data was being generated by bridge inspectors over the years, especially for complex steel bridges,” Shen said. “But you can imagine how difficult it is to track conditions in small, individual, structural critical pieces of each bridge. Even if reports are in the form of electronic PDF’s, it’s a daunting task.

“监测员在数年的工作中已经得到了关于桥梁的大量数据,尤其是复杂钢结构桥梁更是需要频繁的监测以确保其健康状态良好。”沈教授说道,“然而要将众人检测到的关于桥梁结构的那一小部分数据整合起来,并从中追踪桥梁的健康状态,这项任务实在太过艰巨。即使这些数据报告都是易于处理的电子版PDF格式也不能减轻多少工作量。”

 

Shen believes BIM’s ability to incorporate multiple-aspect data into a 3D model makes it ideal for bridge inventory management. The 3D bridge model created using his software enables users to access information relating to bridge conditions in a variety of formats simply by clicking on a specific component within the visual simulation, as opposed to fossicking through a trove of files consisting of dense numerical data which can be hard to comprehend. This enhanced data access makes it far easier for transpo
