群桩基础,简言之就是有很多桩的基础。群桩基础在受荷载工作时会产生群桩效应。这种基础的受力特点是:受荷载后,承台、桩、土的相互作用使其桩侧阻力、桩端阻力、沉降等性状发生变化而与单桩不同,承载力往往不等于各单桩承载力之和,此称为群桩效应。群桩效应和土质、桩的距离、桩的数量、桩的布局方式等各种因素的影响而变化。在建筑高层时,一般都要考虑群桩效应。本论文用通俗的方式,易于理解的语言来解释群桩效应以及粗略介绍关于减少群桩效应的一般措施。
Pile foundation, in short, is a lot of pile foundation. Group pile foundation will produce group pile effect when subjected to load. This foundation is characterized by the force: After the load, the cap, pile, soil interaction so that the pile side resistance, pile end resistance, settlement and other traits change with the single pile, the bearing capacity is often not equal to the single Pile bearing capacity and this is called group pile effect. Group pile effect and soil, the distance between the pile, the number of piles, the layout of the pile and other factors. In the construction of high-rise, generally have to consider the pile group effect. This paper explains the group pile effect in a straightforward, easy-to-understand language and gives a rough introduction to the general measures for reducing pile group effects.
