摘要
结合具体工程实例,介绍了3根超长钻孔灌注桩应用后压浆技术,分析了单桩竖向承载力静载荷试验数据与成果,对压浆前、后各试桩在荷载作用下的沉降量、各试桩桩身截面轴力以及各土层侧阻力作了比较,从而真实而有效地反映出后压浆技术对钻孔灌注桩的作用及显著效果。
In this articel,the author introduces the working procedure and the reinforcing mechanism of the post-grouting technology.According to the data of static loading test for three over-longs bored piles of a project,the author compare the settlement,the axial force distribution along pile shaft and the side resistance of each pile.Base on this analyzed,the noticeable effects on bored cast-in-site piles of the post-grouting technology are reflect veritably and effectively.
