摘　　要：针对软土-隧道体系这样复杂的三维结构,理论分析具有很大的局限性,而上海地区的地铁已运营多年,其隧道的动力性能有了较大的变化,只有通过科学的现场实测,才有可能掌握其动力学性能。现场测试试验安排在上海市地铁某路段,主要介绍了脉动试验的现场试验情况、试验结果及结论。Theoretical analysis on the soft soil-tunnel system which is complicated three-dimensional structure is provided with great limitations. The subway in Shanghai has been operated for many years and dynamic properties about the subway tunnel have changed,which may be controlled by the scientific spot measurement. The experiment is app lied on a certain field in Shanghai subway tunnel. This paper mainly presents the progress of the pulsating detection on the spot and the conclusion.

关 键 词：软土-隧道体系 脉动试验 试验参数 自振频率
