摘要:本文基于全寿命周期的理念，融合桥梁初始设计信息等静态数据、人工巡检、维修记录和实时监测等动态数据，从土建结构、机电系统、附属设施及运营服务四个维度对斜拉桥进行综合评价，提出了基于多维度的评价指标、评价流程与计算方法。同时，针对传统桥梁评价系统的单体架构存在系统耦合度高、错误隔离性差及可收缩性差等不足，以.NET微服务框架为基础，利用C#语言、中间件技术和MySQL数据库设计，实现了斜拉桥在线综合评价系统。通过在上海市某斜拉桥进行应用验证，结果表明评价方法与系统能够满足桥梁评价的业务需求，可有效帮助运营企业进行养护分析，具有一定的实用性。

Abstract: Based on the concept of the life cycle, this paper integrates static data (e.g. the initial design information of the bridge), and dynamic data (e.g. manual inspection, maintenance records, and real-time monitoring data) to conduct a comprehensive evaluation of cable-stayed bridges from four dimensions of the civil structure includes electromechanical system, ancillary facilities, and operational services, and proposes multi-dimensional evaluation indexes, evaluation process, and calculation methods. Given the shortcomings of the single architecture of the traditional bridge evaluation system, for instance, high system coupling, poor error isolation, and poor scalability, based on the.NET microservice framework, the paper designs and realizes the online comprehensive evaluation system of the cable-stayed bridge by using C# language, middleware technology, and MySQL database. Through the application verification of a cable-stayed bridge in Shanghai, the results show that the evaluation method and system can meet the business needs of bridge evaluation, which can effectively help operating enterprises carry out maintenance analysis.
