Application Analysis on Post Grouting Pile in Super High-rise Building Foundation of Tianjin

摘要:

阐述了后压浆技术补强灌注桩的基本原理，并以中海公园城项目为例，介绍后压浆灌注桩在天津软土地区超高层建筑基础中的实践应用，最后通过静荷载实测数据对比分析后压浆灌注桩在提高承载力和降低成本方面的优越性。

Abstract:

This paper describes the basic principle of reinforcing grouting pile by post grout technology and introduces the practical application of post grouting pile in super high-rise building foundation of Tianjin in soft soil area with a project case. The analysis is made on the superiority of post grouting pile in improving the bearing capacity and reducing cost with the comparison of measured static load data.
