基于间断综合测试的桥梁结构状态长效监测方案研究

Research on Long-Term Monitoring Scheme of Bridge Structure Condition Based on Intermittent Comprehensive Testing

摘要:

现有桥梁健康监测及状态评估研究存在成本高、运维难、数据冗余、评估片面等问题，针对这一现实，提出1套基于间断综合测试的桥梁结构状态长效监测方案。介绍桥梁长效监测方案的改进方向、设计原则和基本框架，并以合肥机场路蝴蝶拱桥为例，介绍该桥梁结构状态长效监测方案的基本内容，包括桥梁重点监测部位和监测内容、监测数据的处理分析方法，以及桥梁结构状态的综合评估方法。研究结果表明，该监测方案能够综合传统桥梁检测评估与桥梁健康监测的部分有益成果，可作为现有桥梁结构状态监测手段的有益探索与有效补充。

Abstract:

In view of the problems such as high cost, difficult operation and maintenance, redundant data and one-sided assessment existing in the current research on bridge health monitoring and condition assessment, a set of long-term monitoring scheme of bridge structure condition based on intermittent comprehensive testing is proposed. The improvement direction, design principles and basic framework of the long-term bridge monitoring scheme are introduced. Taking the Butterfly Arch Bridge on Hefei Airport Road as an example, the basic contents of the scheme for this bridge are expounded, including the key monitoring parts and contents of the bridge, the processing and analysis methods of monitoring data, as well as the comprehensive assessment methods for the structural condition of the bridge. The research results show that the proposed monitoring scheme can integrate the beneficial achievements of traditional bridge inspection and assessment, and bridge health monitoring, which can serve as a beneficial exploration and effective supplement to the existing methods for monitoring the condition of bridge structures.
