摘　　要：针对灌注桩在各类建筑工程中的广泛应用,研究了桩底后压浆提高灌注桩承载力的机理,通过对工程实例进行分析,指出灌注桩后压浆施工应从灌浆前压水试验、注浆量、注浆压力、注浆后桩体上抬量等几方面予以控制,才能取得良好的效果。According to the wide application of cast-in-site pile in various kinds of engineering projects, it makes a research on the mechanism of post pressure grouting enhancing the load bearing power of cast-in-site pile. Through the analysis of a project, it points out that post pressure grouting should be controlled from water pressing test, grouting amount and pressure before grouting, and the lifting degree of pile after grouting, so that a good result can be achieved.
