基于交通振动环境下建筑结构损伤机理及减振隔振的研究现状

随着交通建设的发展,越来越多的公路要临近已有建筑物通过,而由于建设或重车通行引起的振动对周边建筑结构产生了很大的安全威胁,严重的甚至造成了建筑结构的损坏。论文通过对交通振动下建筑结构的振动控制标准和在振动中的损伤机理进行综述,系统总结了交通振动对建筑影响的方法,介绍了目前交通振动对建筑结构安全性影响的研究现状和方法,分析了减振隔振的发展现状,创新性的提出将疲劳寿命作为建筑结构振动容许值的参考依据。在总结分析现状的情况下提出目前存在的问题,给出了相关的意见和建议,可为今后的相关研究提供参考。

Research Status of Damage Mechanism of Building Structures and Associated Vibration Reduction and Isolation in Traffic Vibration Environment

With the development of traffic construction, more and more roads have to pass near existing buildings. Therefore, the vibration caused by construction or heavy vehicle traffic poses a great security threat to surrounding building structures, and even causes serious damage. In this paper, the vibration control standards of building structures under traffic vibration and the damage mechanism caused by vibration were reviewed, and the research status and methods for the influence of traffic vibration on the safety of building structures were introduced. The development status of vibration reduction and isolation was analyzed, and the fatigue life was innovatively taken as the reference basis for the allowable value of building structure vibration. Based on the summary and analysis of current situation, the existing problems were put forward, and the relevant opinions and suggestions were given, which can provide reference for future related research.
