摘要
介绍了多支盘钻孔灌注桩的构造及其特点 ,分析了单桩竖直承载力大幅提高的原因 ,并给出了经验公式 ,最后提出了几个需特别注意的问题 .
The structure and characteristic of the multi-under-rea mded cast in situ pile foundation are introduced.The reason why the bearing capa city of the single pile increased so much is given and the empirical formula are discussed. In the last part of this paper,several special problems which need p aying attention to are presented.
