南水北调中线漕河渡槽结构内力计算和钢铰线布置

Calculation of Inner Force and Disposal of Tendon in Caohe River Flume Structure of South-north Water Transfer

南水北调中线总干渠京石段上的一座大型交叉建筑物——漕河渡槽是第一个采用预应力结构的工程。系统地介绍了渡槽结构特点、荷载内力计算、钢铰线数量计算和预压应力复核,以及钢铰线在中、边墙内的布置,为同类工程提供了具体设计实例。

As the large-scale cross structure of total main channel in South-north water transfer, Caohe river flume is the first project introducing prestressed structure.The characteristics of Caohe river flume,calculation of load inner force and tendon, prestressed check and disposal of tendon in side wall are offered for the same project.
