钢筋混凝土灌注桩后压浆作用机理及应用

Impacting mechanism and technique application of post-grouting of bored reinforced concrete pile

从地层选择和后压浆作用机理两方面介绍了钢筋混凝土灌注桩后压浆技术,并结合实际工程,阐明了后压浆是提高钢筋混凝土灌注桩单桩竖向承载力的有效措施,取得了显著的技术效果和经济效益。

In considering various soil layers＇ situation and their respective functional mechanism, this paper presents a bored reinforced concrete pile post-grouting technology. Satisfactory improvement of singular pole vertical bearing capacity resulting from both theoretical analysis and practical construction projects suggests that the application of this technology may achieve remarkable benefits both technically and economically.
