高性能混凝土超高泵送技术在超高层建筑中的应用

Reliability Analysis of Bearing Capacity of C105 Concrete Pipe Pile under Axial Compression

近几年来,我国超高层建筑如雨后春笋般涌现,对高性能结构材料的需要也日益增多,特别是高性能混凝土,C60及以上高性能超高强混凝土已经在多处工程中得到应用。高性能混凝土在超高建筑中的超高泵送技术也因而成为了施工过程中的一项特殊技术。本文通过天津高银117大厦施工实例来研究和分析其中的技术问题。

In recent years, China’s high - rise buildings grow, the need for high performance structural materials are also increas-ing , especially the high performance concrete, C60 and above high performance ultra high strength concrete has been applied in many projects. High performance concrete pumping technology in super high building has become a special technology in the con-struction process. In this paper,the authors study and analyze the technical problems in the case of Tianjin 117 building.
