[摘要] 预应力混凝土管桩用作水平承载桩主要是利用高强的钢筋、高等级混凝土及施加的预应力提供足够的水平抗力来承担外部的水平荷载，水平承载预应力混凝土管桩具有施工速度快、环境污染少、沉桩效率高、经济安全等特点，具有非常广的应用前景。本文在对当前承受水平荷载预应力管桩的理论研究、试验研究及应用现状等方面进行详细分析的基础上，指出了目前用于承受水平荷载的预制桩存在的一些不足，提出了水平荷载下预应力混凝土管桩受力特性中有待研究的问题，为进一步研究高强预应力混凝土管桩在水平荷载下的抗弯承载力提供研究思路。

Abstract: The prestressed concrete pipe pile as the lateral pile is to use high-strength reinforcement, high-grade concrete and prestress to provide adequate horizontal resistance to bear the external lateral load. Because prestressed concrete pipe pile of bearing lateral load has many advantages such as rapid construction speed, less environmental pollution, lught effective pile driving, economicals safe and so on, it has very wide application prospect. Based on the theoretical research, experimental research and application of the current prestressed concrete pipe pile under lateral load, some disadvantages were indicated, and some problems needed to be solved in mechanical characteristics of the lateralload pile had been put forward, which will provide some ideas for further research on the flexural capacity of prestressed pipe pile under lateral load.
