1、目前,预应力混凝土被广泛的使用于各种中小跨度的桥梁中,而且大量采用预应力混凝土将是未来桥梁发展的趋势。在本次毕业设计中,对目前在公路桥梁中经常使用的预应力混凝土简支T型梁桥的设计做了全面的介绍,其中包括调研,外文资料的翻译,方案设计,结构计算以及施工图的绘制。在确定方案时,根据调研及查阅大量的资料,在此桥位上布置了钢管混凝土桥,钢筋混凝土箱型拱桥及预应力混凝土简支T型梁桥三种设计方案,根据“安全,功能,经济,美观叩勺原则,对各种桥型的优缺点进行了比选,而预应力混凝土简支T型梁桥在此桥位上更具有竞争力,反映在工程造价比较低,施工工期短,施工技术成熟,因此,最终选择了预应力混凝土简支T梁桥为设
2、计方案。结构计算着重进行了上部结构的计算,包括截而尺寸的拟定,内力计算(恒载内力,活载内力和附加内力的计算,内力组合以及影响线),配筋设计,施工阶段和使用阶段的应力验算,承载能力极限状态强度验算,刚度验算,变形验算。通过木次毕业设计,进一步加深了我对桥梁以及预应力混凝土的认识。关键词预应力混凝土;T型梁桥;结构计算;设计方案;施工图AbstractNowdays,thepre-stressedconcreteisextensivelyusedinvariouskindsofbridgesofmediumandsmallspan,anditwillbedevelopmenttrendofth
