Due to the wide application of pile foundation, the compacting effect caused by the penetration of jacked pile has influence on the surrounding environment, which have been widely drawn attentions.

由于桩基础的大规模应用，静压桩挤土效应对周围环境产生的影响广泛引起了人们的注意。

The effect of SFRC on mechanics behavior of thick pile caps has also been analyzed systematically in this paper.

对于必须考虑承台作用的低承台群桩，本文的计算结果是很有价值的。

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。
