摘要
某高速收费站综合楼由于地基浸水沉陷,建筑物地基产生不均匀沉降,墙体裂缝严重。论文通过该建筑的静压桩地基加固实例,阐述静压桩施工技术及施工中遇到问题的应对方法,得出在桩头与桩尾安装钢套筒的方法可以极大增强连接处的抗弯、抗剪性能,并能有效杜绝桩头爆桩的发生。
Due to flooding subsidence of a high-speed toll station foundation in Gansu province, uneven settlement happened on the building foundation, wall cracks was serious, this paper took the construction of static pressure pile foundation reinforcement as an example, static pressure pile construction technology and encountered problems in the construction approach were discussed, installed steel sleeve of the pile and pile tip can improve the bending and shear property and completely eradicate pile
