大容量预应力混凝土软横跨接触网支柱的研制

Research and Development of Great-capacity Pre-stressed Concrete Catenary Posts with Flexible-cross

文章介绍了代替软横跨接触网钢柱的大容量预应力混凝土软横跨接触网支柱的荷载计算、结构分析和内力计算方法。并通过支柱的卧式和立式对比试验 。

The paper introduces the load calculation,structrual analysis and internal force calculation method of the great capacity flexible cross pre stressed concrete catenary post which replaces the flexible cross steel catenary posts.It proposes that the sleeping type test be used to test the structural performance of the post that is subject to bi directinal loading.
