摘要
桩基础在土木工程中应用极为广泛,尤其是港口工程。通过总结港口工程中常见的几种桩基础,包括钻孔灌注桩、预应力混凝土桩、PHC桩和钢管桩在设计与施工中的一些特点,同时介绍工民建工程中人工挖孔桩和钻孔灌注桩以及桥梁工程中冻土、岩溶地区桩基的施工特点,为不同工程条件下港口工程桩基设计及施工方案的选择提供参考。
Pile foundations are widely used in various civil infrastructures,particularly ports and marine facilities.This paper summarizes the current practice of design and construction for the typical types of pile foundations applied in ports and marine structures,such as cast-in-place bored pile,prestressed concrete pile,PHC pile,and steel tubular pile.The practice of design and construction for pile foundations in buildings and bridges is also reviewed.This paper provides practical information for selecting the appropriate pile type in a given marine project.
