摘要
后压浆技术能改善桩端沉渣和桩周泥皮。通过某工程压浆试验,表明后压浆工艺能大幅度提高基桩承载能力,减小沉降量,并结合分布式光纤检测得到了桩身侧摩阻分布图,对压浆效果及作用机理进行了直观地分析。
Post-grouting technology can improve the disadvantage of bored piles. It has been proved that post-grouting technology can advance the bearing capacity and reduce the settlement of pile markedly by some post-grouting experimentation. Side frictional resistance distribution map of pile has been gained according to distributed optical fibre detection, and post-grou ting effect and mechanism of action are also analysed.
