大直径PHC管桩在软土地基工程中的应用

The application of large diameter phc pipe pile in soft soil foundation engineering

本文通过分析小直径(Φ500、Φ600)预应力混凝土管桩在软土地基中应用的局限性,结合工程实例,通过对大小直径预应力混凝土管桩力学性能的对比分析,论证大直径管桩(Φ800)在软土地基工程中应用的可行性,并分析其经济性及施工注意事项。

In this paper,based on the analysis of application limitations of small diameter（ Φ500、Φ600） prestressed concrete pipe pile in soft soil foundation,combined with practical engineering,do an analysis of the mechanical properties between large and small diameter prestressed concrete pipe pile,finally demonstrated the feasibility of application of large diameter（ Φ800） pipe pile in soft soil foundation engineering,at the same time,analyze it’s economy and the matters of construction attention.
