先张法空心板梁的设计计算要点

Design and Computation Gist of Pre-tensioned Hollow Plate Girder

该文介绍了先张法空心板梁的设计计算要点。随着我国交通事业的发展,建造了大量的公路、市政桥梁,中小跨径的桥梁占了绝大多数,而其中又以先张法空心板梁桥为主,量大面广的先张法空心板梁桥直接关系着我国道路网络的安全畅通和有效服务,所以弄清楚先张法空心板梁的设计计算来确保桥梁工程的质量具有非常重要的现实意义。

The article introduces the design and computation gist of pre-tensioned hollow plate girder.With the development of the traffic facilities in China,a number of highway and municipal bridges have been constructed,in which the most are the small and middle-span bridges mainly with the pre-tensioned hollow plate girders.The large quantity and wide range of pre-tensioned hollow plate girder bridges is directly related to the safe smoothness and the efficient service of road network in China.Therefore,good to understand the design and computation of the pre-tensioned hollow plate girder is very important to ensure the engineering quality in China.
