1、空心板桥设计说明书摘要我国自改革开放以来，路桥建设得到了飞速的发展，这对改善人民的生活环境，改善投资环境，促进经济的腾飞，起到了关键的作用。本课题研究的是辽阳境内的柳壕河，通过方案比选，确定预应力空心板桥最为经济合理。此河处于市郊，区域内无不良地质现象，属于稳定性河段，抗震有利地段，在此河上建造一经济合理，适用性强的桥梁，来满足两岸经济的发展，方便人们的生活需要。本设计包括一整套系统设计方案，包括水文计算、内力计算、主梁预应力钢筋布置、预应力损失计算、应力验算、支座计算、桥台设计、盖梁计算、桥墩计算和基础计算等，并且绘制详细的三方案平、立、剖面图，主梁剖面图，主梁配筋图，盖梁
2、配筋图，桥墩配筋图，桥台构造图，承台配筋图，支座构造图和伸缩装置构造图。本设计采用预应力空心板桥，它不仅能减轻自重，而且能充分利用材料。此空心板挖空率较大，自重较轻，它的技术较先进，制作工艺成熟，施工方便，制造简单。其结构质量安全可靠，耐久性能好，计算简便。钢材用量小，安装方便，施工工期短，造价低，适合柳壕河地质状况。本设计基本满足技术先进、安全可靠、适用耐久、经济美观的要求。关键词：预应力空心板桥；盖梁；桥台；承台；桥墩IIAbstractSinceChina’sreformandopeningup,therapiddevelopmentofroadandbridgecon
