摘　　要：随着大跨径混凝土斜拉桥在公路中的广泛使用,针对传统的桥梁监测系统存在着监测不连续、监测系统功能单一、数据冗余和监测结果不准确等诸多缺点,不能满足桥梁监测自动化、智能化的需要,提出大跨径混凝土斜拉桥施工运营一体化监测系统的总体设计思路和系统架构,论述了系统的开发目标和功能需求,并对各个功能模块的设计及实现的关键技术进行探讨。系统充分利用了计算机系统强大的数据计算和管理功能以及ANSYS软件的结构分析功能,提供对桥梁的实时自动化、智能化监测、3D动态仿真和预警服务,系统的开发将为桥梁监测工作提供新的思路与手段。With the widespread using of long-span concrete cable-stayed bridge in road engineering,many traditional bridge monitoring systems can't meet the requirements of automation and intelligence because the shortcomings such as single function,date redundancy and the inaccurate monitoring results.This paper puts forwards system design and system structure of the long span concrete cable-stayed bridge construction-operation integrated monitoring system and discusses its development goals and functional requirements,and introduces the function of each module and key technology.The system provides the services such as real-time and automotive and intelligent bridge monitoring and 3D dynamic simulation and early warning,based on making full use of the powerful data calculation and management functions of computer system and the analysis capabilities of the ANSYS software.The development of this system will provide new ideas and means to the bridge monitoring work.
