pile driving

基本解释

Based on the cylindrical cavity expansion theory, the squeeze stress induced by pile driving in soils around a pile and inside cluster of piles is analyzed.
本文根据圆柱孔扩张理论分析了在单桩周围和群桩内部土中产生的打桩挤压应力，并与室内模型试验和工程实录资料作了比较。
Excitation force needed by pile driving machinery are comprehensive determined by site soil, soil condition, moisture content and type of pile, construction.
打桩机械所需要的激振力要根据场地土层、土质、含水量及桩的种类、构造而综合确定。
The bucket foundation suction penetration technique is different from the pile driving technique, and the characteristics of penetration resistance is greatly influenced by the seabed character.
桶形基础采用负压沉贯法施工，与压桩、打桩等施工方法显著不同，且阻力特性受地基性质影响很大。

沉桩
In view of this,the thesis advanced a new "bring to an end" criterion in vibratory piling process,which provide a theoretical basis for ending pile driving.
据此，通过分析和研究，本文提出了一种在振动条件下沉桩的“收锤”准则，为振动沉桩施工收锤提供了理论依据。
打桩
The attenuation characteristics of ground vibrations caused by pile driving were proposed.
从而得到了打桩引起地面振动衰减特性。
