摘要
为了研究连续型荷载作用下的单排桩隔振效果,分别研究了桩长,桩径,桩间距与振源距等因素对其隔振效果的影响。并通过室外试验,以连续型荷载作为振源,对单排桩在以地表振幅降低比作为评价指标的基础上进行分析,得出结果表明:增加桩长和增大桩径对增加隔振效果有益。减小桩间距和振源距离对隔振效果较好。
In order to study the isolation effect of single row pile under continuous load,the effects of pile length,pile diameter,pile spacing and vibration source distance on the isolation effect are studied.Through the outdoor test,the continuous load is taken as the vibration source,and the single-row pile is analyzed on the basis of the surface amplitude reduction ratio as the evaluation index.Reduction of pile spacing and vibration source distance is good for vibration isolation.
