【摘要】 预应力高强混凝土管桩(简称PHC桩)具有强度高、耐久性好、施工快、造价低、检测方便的特点,现已广泛应用于电力、工业与民用建筑、桥梁、港口码头等工程。采用PHC桩作为建筑物基础,可充分发挥其强度高的特点,从而提高基础的承载力。介绍彭家湾泵站和水闸工程中采用预应力高强混凝土管桩基础及PHC桩的设计和主要施工工艺。更多还原

【Abstract】 Prestressed high strength concrete pipe pile( PHC pile) has been widely used in the construction of electric power stations,industrial and civil buildings,bridges,ports and other projects due to its characteristics of high strength,good durability,quick construction,low cost,detection convenience. When adopted as the structure foundation,its characteristic of high strength can be fully realized,and thus the bearing capacity of the foundation can be largely improved. In this paper,the design and construction technology of PHC pile foundation in Pengjiawan Pumping Station and Sluice Project are introduced.更多还原
