修建于上世纪的石拱桥大部分已经进入超期服役阶段，其技术状态直接影响车辆通行安全，而结构参数的变异性以及结构响应理论值的不确定性给桥梁评定造成一定困难。本文以一座石拱桥为试验对象，提出了一套适用于既有石拱桥技术状态的评定方法。该方法融合了外观调查、静载试验两者的优势，通过分析施加荷载与结构响应的关联程度推断桥梁的承载能力。

Stone arch bridge built last century has been used longer than their designed service life,and the problem of operation safety shall be noticed. It is difficult to evaluate the bridge since the variability of structure parameter and the uncertainty of structure response. In this paper,a stone arch bridge w as studied. An approach w as proposed for evaluation of existing stone arch bridges. T he method has the advantage of both observation and static load testing. T he bearing capacity of the bridge may be assessed through the relationship between the load and the structural response.
