摘要
如何准确把握在役桥梁的工作状态,了解其实际承载力是目前倍受关注的课题之一。首先概述了当前桥梁结构性能评价方法的发展状况,讨论了静力荷载试验评价方法与动力试验评价方法的内在区别与联系,并基于二者的联系在理论上建立了桥梁结构性能综合评价指标。最后以一工程案例详述了综合评价指标在桥梁结构性能评价中的应用方法,以期为相关研究提供借鉴。
How to accurately grasp the state of bridges in service and understand the actual carrying capacity is one of the topics which are attracting the most attention.This paper firstly gives an overview of the development state of current method for evaluating bridge structural capability,and then discusses the internal differences and ties between the evaluation of static load test method and dynamic test evaluation method.Subsequently,a compositive evaluating index for bridge structural capability is established in theory,based on the contacts of the foregoing two kinds of capability evaluating methods.Finally,with the hope of providing a reference for relevant studies,the application of the compositive evaluating index is stated in detail.
