摘要
为利用监测信息自动对桥梁地基基础的安全性进行评估,在介绍润扬大桥地基基础监测系统的基础上,基于层次分析法的基本原理,提出了润扬大桥南汊悬索桥地基基础安全性评估的层次结构与体系,并在力学机理分析的基础上以百分制形式定量给出各个因子的评分标准。应用表明,由于本方法将专家确定权值与利用现场监测信息计算各个因素分值相结合,便于实际应用,多次评估结果能够准确地反映了桥梁基础的安全状况。
In order to use monitoring information to evaluate the safety of bridge foundation, based on the introduction of the Runyang Bridge's foundation monitoring system, the layer sequence structure and system of the foundation safety assessment of the southern suspension bridge was brought forward according to the analytic hierarchy process fundamental principle. Based on the mechanics mechanism analysis, the evaluation criterion of each factor was given by percentage. Which indicates that it is convenient for application because this technique makes the weight ascertained by expert and the evaluation of each factor calculated by the monitoring information in site together, and many evaluation results can reflect the safety of the bridge truly.
