    摘要:

    桥梁结构模型试验作为了解结构真实受力行为及传力机理最有效的手段之一,在学术界和工程界应用广泛。总结了2019年桥梁模型试验的研究进展,从静力模型试验、疲劳模型试验、振动台模型试验和混合试验4个方面评述了典型案例以及依托模型试验开展的关键科学问题研究;并总结了模型试验相关的新型测试技术。总结发现,桥梁模型试验是探究桥梁结构新设计、新工艺、新材料安全性、耐久性及适用性的重要手段,也是准确估计桥梁结构剩余寿命或承载能力的有效方式;针对模型试验发展的测试技术主要集中在结构应变、变形、加速度、温度测试,以及结构缺陷识别等方面。对桥梁模型试验与新型测试技术的发展进行了展望。

    Abstract:

    As one of the most effective means to understand the real mechanical behavior and transmission mechanism of the structure, the bridge structure model test has been widely used in the academic and engineering fields. In this paper, the research progress of bridge model test in 2019 is summarized. The typical model test applications and the key scientific issues based on model test are reviewed from four aspects: static model test, fatigue model test, shaking table model test and hybrid test. In addition, this paper also summarized the new testing technology related to model test.Through the summary of this article, model test is an important method to investigate the safety, durability and suitability of bridge structures which use new design, new technology, and new material. And its also an effective method to evaluate the residual life or bearing capacity.The testing technology related to the development of model test mainly focus on measurement of strain, deflection, accelerated velocity, temperature, defect identification and so on.In the end of this paper, the development of bridge model test and new testing technology is prospected.
