| 摘 要： | 文章提出一个新的横张预应力混凝土梁桥建造工法,扩大了横张预应力混凝土的适用范围。该工法利用虚功原理和平衡构形概念,通过双榀对称侧立预制空心梁的方法,以接近普通钢筋混凝土的价值,可制作得预应力混凝土,进一步降低了预应力混凝土桥的建造难度,提高了施工的可靠性,具有一定的技术、经济和社会效益。

| Abstract: | In the Paper,a new construction method for transverse tensioning prestressed concrete bridge has been proposed,which will enlarge the application scope of transverse tensioning prestressed concrete. With reference to the virtual work theory and equilibrium configuration philosophy,this construction method can produce prestressed concrete at the cost similar to that of normal concrete by means of double-beam side-precasting hollow beam method. It thus further mitigates the construction difficulty of prestressed concrete bridge and improves construction reliability,and as well brings about technical,economic and social benefit. |
