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．
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.
