摘要
阐述了桩底后压浆提高灌注桩承载力的机理,结合具体的工程实例,介绍了钻孔灌注桩后压浆技术在工程中的应用,并对其试验结果作了分析,指出该技术能大幅提高桩基承载力,减少桩基沉降。
Combined with concrete example of project,it illustr at es mechanism of post-pressing mortar at bottom of pile increasing bearing force of grouting pile,introduces its application in project,analyses its experimenta l results,and points out that this technology increases bearing force of pile fo undation & decreases subsidence of pile foundation highly.
