排桩隔振试验分析

Analysis on row pile vibration test

基于实体桩现场测试试验的基础上,研究了饱和土地基中非连续屏障对振动的隔离,分析了饱和土体渗透性对非连续屏障隔振效果的影响,研究表明在一定条件下,实芯桩的桩径对隔振有一定影响,随着桩径的变大,隔振效果逐渐变好,通过动态分析测试系统对测点三个方向检测,可得振动对于场地在三个方向上的影响是不一样的,对于两排组合桩与单排桩的比较,本试验组合桩的隔振效果比单排桩效果大致相差不大。

On the basis of solid pile field test experiment, study the non isolated continuous barrier on the vibration of the saturated soil, analysis of saturated soil permeability on the discontinuous barrier effect on the vibration isolation. Research shows that under certain conditions, solid core pile diameter on the isolation has certain effect, as the pile diameter becomes larger, the vibration isolation effect becomes better, through dynamic analysis of test system for measurement in three directions, but the vibration is not the same effect on the site in three directions, com- pared to the two rows of piles and single pile, the pile vibration isolation effect than single row pile effects are generally little difference.
