摘　　要：随着快速轨道交通的发展,轨道交通运行所带来的振动影响越来越严重,而已有的轨道交通运行引起的场地振动实测研究,大多集中在列车速度较低的情况下,已无法解决现行问题。本文通过对轨道交通运行引起的场地振动的现场测试进行评述,总结了目前该实测研究中存在的问题,提出尚需进一步研究的建议。今后的研究需综合分析各种因素对地面振动和地基动应力的影响,从而更好地控制振动,以便提出有效且经济的减振隔振措施,以期为该领域的深入研究提供一些建设性意见。The existing field measurement on ground vibration induced by rail transit operation mostly concentrates on the trains at relatively low speed cases.With the development of rapid rail transit,the vibration effect brought by rail transit operation is becoming more and more serious.The existing research is unable to solve the current problem.Through reviewing the current research on the field measurement of ground vibration caused by rail transit operation,this paper summarizes the problems existing in the research and some suggestions on further research are put forward.For future research,it is needed to analyze the effect of various factors on the ground vibration and the dynamic stress of foundation comprehensively.This will be able to control vibration better and provide effective and economical vibration reduction and isolation measures,and it will be also beneficial to the creation of a secure,harmonious environment and a environment-friendly society.
