Therefore, not only the pile spacing but also the pile group layout will have influence on both the bearing capacity and the pile group effect of pile groups.
群桩已不再具有圆形单桩的轴对称性，因此群桩的承载特性及群桩效应不仅受桩间距的影响，而且受群桩布置方式的影响。
Compared with the existing methods, the proposed method could obtain more reasonable results which could decrease pile group effect and render a distribution of pile head load agreeable to the fact.
与现有的方法相比，该方法能够取得较好的结果，即使群桩之间被夸大的效应减小了，桩顶荷载的分布更趋于实际工况。
Reducing well spacing can economize project cost, but it will cause group pile effect and bring on the phenomenon of repelling hammering.
减小井距可节约工程费用，但会引起群桩效应而导致拒锤现象发生。
In the course of studying on pile group under its model test, it is discovered th at the measured value of effect coefficient of pile group is larger than that in the codes table.
在进行群桩模型试验研究过程中，作者发现实测群桩效应系数与规范表中相应的数值存在较大差异。
It is found from the analysis under special situation that the large axial load had obvious effect on dynamic interaction factor of group pile.
通过分析表明，在轴向力作用较大的情况下，动力相互作用因子的影响较为明显。
