摘要: 在总结已有预应力砼技术优缺点的基础上,提出了预弯双预应力复合梁、预弯预应力钢筋砼、预弯无粘结预应力砼、横张预应力砼技术的构思.其中,横张预应力砼技术集良好的使用性、用材的经济性和施工的简易性于一体,具有很好的技术经济效益和推广应用前景.

关键词: 预应力砼, 预弯复合梁, 横张预应力

Abstract: The advantages and limitations of the main types of existent prestressed concrete techniques are discussed in this paper.Several new types of prestressed concrete techniques are proposed preflex bi-prestressed composite beams, preloaded prestressed concrete beams, preloaded prestressed concrete beams with unbonded tendons and vertically tensioned prestressed composite beams.The last types is discussed specifically.

Key words: prestressed concrete, preflex beams, vertically tensioned prestress
