摘要
实现土木工程的智能监测和评估是一项复杂的涉及多理论与技术交叉的系统工程。提出了一种土木工程结构智能监测与评估系统,可为核电厂房、大跨桥梁、工业建筑等大型土木工程、基础公共设施的安全运行与科学管理提供技术支持。该系统主要有监测系统、计算及评估系统、可视化系统组成,主要功能为对工程结构进行实时、有效的监测,并对监测数据进行处理、分析,同时根据结构的具体特点,借助数字映像技术和快速且科学的算法,计算得到结构的内在物理本质,对结构各种工况进行模拟、分析和研究,评估结构的安全性,并通过计算机图形显示技术,客观、真实地将结构状态予以显示。通过两个应用实例,说明采用该土木工程智能监测和评估系统不仅可实现监测信息的实时有效采集、传输和存储,而且借助快速、科学的算法,可得到结构的实际性能情况,并进行三维可视化展示,为土木工程安全建设、运行、科学管理和决策提供技术支持。
It is a complex project to realize intelligent monitoring and evaluation in civil engineering involving the intersection of multiple theories and technologies. An intelligent monitoring and evaluation system in civil engineering structures(MDCRS) was put forward, which could provide technical support for the safe operation and scientific management of large civil engineering and basic public facilities such as nuclear power generating stations, long-span bridges and industrial buildings. The system was mainly comprised of a monitoring system, a calculation and evaluation system, and a visualization system. Its main functions were as follows: implementing real-time and effective monitoring in engineering structure, processing and analyzing monitoring data, getting the inner physical nature of the structure by a fast algorithm and digital mapping tenchnique according to the specific characteristics of the structure, conducting simulations, analysis and research of various working conditions of the structure to assess structural safety, and displaying the structure state objectively and truthfully through the computer graphics display tenchnique. Two application instances were taken in the paper to illustrate the fact that the civil engineering intelligent monitoring and evaluation system could not only realize real-time and effective collection, transmission and storage of monitoring information, but also obtain the actual performance of the structure by a fast and scientific algorithm, further, could conduct a three-dimensional visual display and provide technical support for safe construction, operation, scientific management and decision-making in civil engineering.
