某高层建筑素混凝土桩复合地基的设计

Design of Concrete Pile Composite Foundation in Tall Building in Shijiazhuang

通过石家庄某高层建筑地基采用素混凝土桩加固处理的工程实例,对素混凝土桩在复合地基中的设计和沉降进行了分析,着重介绍了桩长、桩径、桩间距、桩体强度、褥垫层厚度等设计参数的确定,可供设计者参考。

Combining with the engineering practice of ground improvement by adopting concrete piles for a residential building in Shijiazhuang, an analysis of the design and after construction settlement of concrete piles applied for composite foundation improvement are carried out in this paper, especially the design parameters of concrete piles are emphatically introduced including pile length, pile diameter, pile spacing, pile strength, thickness of mattress layer and so on, which could be a reference to the designer.
