摘要
为评估轨道交通致振对重点实验室的影响。文中基于实际工程应用类比试验和有限元模拟评估影响,探究可用于重点实验室评估方案,给出重点实验室减振建议。研究结果表明,实际工程中轨道交通致振影响均满足规范要求,对实验室可采用类比试验和有限元模拟相结合进行致振评估,若轨道交通致振对重点实验室的影响过大,建议先进行轨道减振,再考虑结构的局部隔振。研究成果可为类似工程提供借鉴。
In order to evaluate the impact of rail transit vibration on key laboratories,according to the actual engineering application analogy test and finite element simulation evaluation impact,exploring the evaluation plan can be used for key laboratories,and give key laboratory vibration reduction recommendations.The results showed that the environmental impact of the vibration caused by rail transit in the actual project meets the requirements of the specification.A combination of analog test and finite element simulation can be used to evaluate the vibration in the laboratory.If the vibration caused by rail transit has too much impact on the key laboratory,it is recommended that the track vibration be reduced first,and then the local vibration isolation of the structure should be considered.
