PHC管桩水平承载力试验与设计构造

Test and Design Construction for PHC Pipe Piles in Horizontally Loading Bearing Capality

预应力高强混凝土管桩(简称PHC桩)因承载力高,施工方便,造价低,近年来许多地区特别是抗震设防地区得到广泛应用,但其水平承载力特性研究较少。通过3根PHC管桩水平力作用下的试验,研究PHC管桩水平承载力性状,提出采用PHC管桩在设计与构造上的一些建议。

pipe piles of prestressed high strength concrete （referred to PHC piles ）for high bearing capacity ,construction is convenient ,low cost are extensively applied in many areas ,especially the earithquake fortification zones,respect of its horizontal carrying capacity properties theoretical research is so rarely .this paper for experimental study on horizontal loading of three pipe piles of prestressed high strength concrete, introduces the behavior of PHC pipe piles under horizontal loading bearing capacity. Provide some suggestions forpipe piles in design and construction.
