部分预应力混凝土桥墩盖梁设计方法研究

摘要

分析了部分预应力混凝土桥墩盖梁的设计要点，阐述了部分预应力混凝土桥墩盖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盖梁设计比较，发现部分预应力混凝土盖梁兼有全预应力混凝土和钢筋混凝土的优点。%The design elements of partially-prestressed concrete pier cap beam,and explained the design concept and method of partially-pres-tressed concrete pier cap beam. Analysis the calculations of partially-prestressed and fully-prestressed concrete cap beams,which show partially-prestressed concrete cap beam has the advantages of both fully-prestressed concrete structure and reinforced concrete structure.
