预应力砼新技术探索

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

Exploration of New Technologies for Prestressed Concrete

On the basis of summarizing the advantages and disadvantages of existing prestressing concrete technology, the concepts of pre-bending double prestressing composite beam, pre-bending prestressing steel reinforcement concrete, pre-bending non-bonding prestressing concrete, and cross-tensioning prestressing concrete technology are proposed. Among them, the cross-tensioned prestressed concrete technology combines good usability, economy of materials and simplicity of construction, and has good technical and economic benefits and prospects for popularization and application.
