摘要
跨座式单轨PC(预应力混凝土 )轨道梁桥结构具有承重、导向及稳定的作用。阐述了作用于PC轨道梁桥结构上的荷载 ,曲线PC轨道梁的内力计算 ,预应力计算 ,应力计算及组合。简要介绍了PC轨道梁的支座、伸缩指形板及梁内或梁上预埋件的设置。
Straddle type single track beam of Press Steel Concrete (PC) possess the action of bearing, orienting and stabilizing. The article have expounded the load acting on PC single track beam, and the calculation of curved PC single track beam including force, prestress and the stress etc. At the same time, the article introduce concisely the setting of bearings, extension finger plate and the pre buried elements in the beam.
