部分预应力混凝土桥梁设计方法的研究

Study of Design Procedures for Locally Prestressed Concrete Bridge

分析了部分预应力混凝土桥梁的设计要点、阐述了部分预应力混凝土桥梁设计思想和设计方法。通过对部分预应力与全预应力混凝土桥梁设计比较,发现部分预应力混凝土桥梁,兼有全预应力混凝土和钢筋混凝土的优点。

The paper analyzes the essentials for design of locally prestressed concrete bridge, expounds the design ideas and procedures for present bridge. By contrasting the design of locally prestressed concrete bridge to one of fully prestressed concrete bridge, it is discovered that the locally prestressed concrete bridge has yet the merits of fully prestressed concrete and reinforced concrete.
