摘　　要：桩基工程中,UHC超高强混凝土管桩针对现预制混凝土管桩的缺点不足而研发应用,超高强混凝土为混凝土强度等级C105以上的管桩,分为C105和C125两种等级,桩身强度的再次提高,使得超高强混凝土管桩具备更大的承载力和桩身强度,能够满足更复杂土质情况的施工条件。In pile foundation engineering,UHC ultra-high-strength concrete pipe piles are developed and applied in view of the shortcomings of existing prefabricated pipe piles.Ultra-high-strength concrete is a pipe pile with a concrete strength grade of C105 or above,which is divided into two grades:C105 and C125.The strength of the pile body is improved again.Concrete pipe piles have greater bearing capacity and pile strength,and can meet the construction conditions of more complex soil conditions.
