港口陆域建筑预应力混凝土管桩设计

Design of prestressed concrete pipe piles in harbor land area buildings

随着港口建设的不断发展,港口陆域建筑越来越多地采用预应力混凝土管桩。基于港口陆域建筑工程设计、施工经验,结合港口陆域建设场地地质条件,参阅有关文献资料,通过对预应力混凝土管桩自身特点、沉桩机理等分析,对预应力混凝土管桩的构造、沉桩工艺及成桩后的质量检测等进行探讨,并提出一些改进建议,供设计和施工参考。

With the development of harbor construction,prestressed concrete pipe piles are more and more widely used in harbor civil engineering.This paper probes into the structure of prestressed concrete pipe piles,piling technology and quality inspection after construction based on the design and construction experience of port land area building engineering,according to the geologic condition of the construction site,and through analyzing the characteristics of the prestressed concrete pipe piles and the piling mechanism,also referencing related documents and information.Some suggestions on the improvement are put forward to serve as a reference for the design and construction.
