Field Measurement and Analysis on Vibration Isolation Effects of Multi-rows of Piles for Railway Engineering

利用排桩隔振屏障隔离列车运行产生的振动是治理铁路环境振动的有效手段。本文结合排桩隔振的工程实例,实测了距离铁路不同距离处排桩的隔振效果,分析了隔振效率和隔振特性,同时对排桩排数对减振效果的影响进行了实测和分析。研究成果可为通过排桩隔振屏障治理铁路环境振动的相关工程提供技术参考。

Using the multi-rows of piles as vibration isolation barriers to isolate the vibration generated by train operation is one of the effective measures to control railway environmental vibration. Combining with engineering project of multi-rows of piles for vibration isolation,the vibration isolation effects of the multi-rows of piles at different distances fromthe railway were measured,the vibration isolation efficiency and vibration isolation characteristic were analyzed,and the influence of pile rownumber on the vibration damping effects was measured and discussed. The results could provide a reference for the railway environmental vibration isolation control and management engineering with multi-rows of piles as vibration isolation barriers.
