摘　　要：随着城市的发展,高层建筑越来越多,地下室也越来越多越来越深,静压高强预应力管桩(PHC)为符合设计的抗压、抗拔要求,桩长就要求越来越长。结合工程,文章介绍了用静压机施工,用不同类型的桩尖在砂层中入土深度的不同。With the development of the city, there are more and more high-rise buildings, the basement is growing more and more deep, PHC （PHC） to meet the design requirements of compression, uplift, pile length requires more and more long. Combined with the project, the paper introduces the constructi-on of static press, the different penetred depth of using differe-nt types pile tip.
