部分缆索承重梁桥的概念设计

摘要

This paper puts forward the concept of partial y cable-supported girder bridge, expounds the design principle,characteristics and application scope of this kind of bridge. At the same time, points out the method to determine the cable force and cable layout characteristics of this kind of bridge . At last, three design examples of this kind of bridge are introduced.%本文提出了部分缆索承重梁桥的概念，阐述了该类桥型的设计原理、特点和适用范围。同时指出这类桥梁的拉索布置特点和成桥索力的确定方法。最后介绍了该类桥梁的三个设计实例。
