灌注桩后压浆技术解决了桩底沉淤和桩身泥皮影响灌注桩承载力的问题,使桩底、桩侧土得到了加固,从而大幅度提高了灌注桩的承载力,降低了桩的沉降量。本文通过对某高层住宅大直径后压浆灌注桩和普通钢筋混凝土灌注桩的设计及静载对比试验,说明了后压浆灌注桩是一种承载力高、经济效益显著的桩型,在太原市地质条件下,值得推广应用。 Grouting after grouting technology to solve the pile bottom silt and pile mud affect the bearing capacity of piles, so that the bottom of the pile, the side of the soil has been reinforced, which greatly improved the bearing capacity of piles, reducing the pile Of settlement. This paper through a high-rise residential large diameter grouting pile and ordinary reinforced concrete bored pile design and static load comparison test shows that the post-grouting bored pile is a bearing capacity is high, significant economic benefits of the pile, in Taiyuan City geological conditions, it is worth promoting application.
