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。
It is also important to assess the driveability of the selected pile to assure that the required capacity and penetration depth may be achieved at a reasonable driving resistance.
同样重要的是，它的操控性能评估以确保其选择桩所需的能力和穿透深度可在一个合理的行驶阻力。
The value of frictional force of soil to pile body and resistance to pile toe has a close relation with the penetration depth and relative rigidity of soil layer at pile body and pile toe.
支承桩的桩身摩擦力和桩尖阻力的大小与入土深度及桩身、桩尖处土层的相对刚度密切相关。
