[摘要] 預(yù)應(yīng)力混凝土管樁用作水平承載樁主要是利用高強(qiáng)的鋼筋、高等級(jí)混凝土及施加的預(yù)應(yīng)力提供足夠的水平抗力來承擔(dān)外部的水平荷載，水平承載預(yù)應(yīng)力混凝土管樁具有施工速度快、環(huán)境污染少、沉樁效率高、經(jīng)濟(jì)安全等特點(diǎn)，具有非常廣的應(yīng)用前景。本文在對(duì)當(dāng)前承受水平荷載預(yù)應(yīng)力管樁的理論研究、試驗(yàn)研究及應(yīng)用現(xiàn)狀等方面進(jìn)行詳細(xì)分析的基礎(chǔ)上，指出了目前用于承受水平荷載的預(yù)制樁存在的一些不足，提出了水平荷載下預(yù)應(yīng)力混凝土管樁受力特性中有待研究的問題，為進(jìn)一步研究高強(qiáng)預(yù)應(yīng)力混凝土管樁在水平荷載下的抗彎承載力提供研究思路。

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.
Keywords: lateralload; prestressed concrete; flexural capacity; pipe pile
