摘　　要：挤扩支盘桩是近几年得到较大范围应用地一种新型桩基,它是在直杆支承桩的基础上,根据不同土层可以挤扩多节支盘,从而可以大大提高桩的承载力,缩短工期,提高工程质量,减少混凝土用量和节约投资。Bored pile with partially expanding diameter is a new type of pile. When drilling a constant hole, at particular depth where certain type of soil layer suitable for extruding exists, enlarged diameter part may be reamed to form several enlarged part along the concrete pile so as to improve bearing capacity of the pile. This method may shorten construction duration, save concrete, secure quality, being cost effective as well.
