预应力混凝土管桩在湿陷性黄土地区的应用

The Application of Prestressed Concrete Pipe Pile in Collapsible Loess Zones

分析了二元桩型(土挤密桩+混凝土钻孔灌注桩)、预应力混凝土管桩复合地基两种地基处理方案,在确保结构安全可靠的前提下,提出了更为经济合理的形式,为同类工程提供了宝贵经验。

This paper makes the analysis on two soil treatment schemes of the binary pile （the soil compaction pile ＋ concrete cast-in-situ bored pile） and the prestressed concrete pipe pile composite foundation, and under the precondition of ensuring the safety and reliableness of the structure, puts forward a more economic and rational form, which provides valuable experiences for the similar projects.
