锚杆静压桩补强加固人工挖孔桩基础

Enhancement of the man-bored pile foundation through the anchor statically-pressed pile

人工挖孔桩基础在施工中若达不到设计要求,且又不能用相同桩基进行补救。文章通过介绍桩基础加固实例,阐述了锚杆静压桩桩基础补强加固时的基本原理;设计需要综合考虑的各种因素以及施工时应注意的要点;从理论探讨到实际施工都有详细说明,以及补强加固的效果,均有详细论述,对其它类似的工程施工质量事故有一定的参考意义。

The manbored pile foundation can not be enhanced by the same kind of pile when it can not meet with the design requirements during construction. In this paper,the fundamental principle of the manbored pile foundation enhancement through the anchor staticallypressed pile is introduced based on one engineering example. Some factors and the key construction points which should be thought about during the design,and the effect of the enhancement are discussed in detail. The presented wok may be beneficial to the construction of other similar engineering.
