1、本设计为寒亭区某T型梁桥,该桥位于某二级公路,规划河道宽度为39m,共分3跨。横率为1.5%o河底标高3.2m,水面线高程5.2m,梁底高程8.2mo沥青混凝土铺装5cm;混凝土铺装10cm,主梁截而强度验算时计入8cm的铺装参与受力。简支梁标准跨径13m,净2X3.5+2X0.5m。采用装配式钢筋混凝土T形简支梁桥。设计中用到所学的各类知识,在设计中得到综合运用,通过不断的查阅资料,整理计算,思考,计算出各个部分。在设计过程中遇到的一些问题,通过查阅资料,询问指导老师,解决了遇到的各种困难。设计遵循符合设计要求,研究内容有学术和实
2、用价值,论述充分翔实,逻辑性强,能反映出运用所学知识分析问题,解决问题的能力,论文语句通顺,条理清晰,论证严密深刻,结构严谨,行文规范,并且在规定时间内做出。本设计包描上部结构布置,主梁内力计算,承载能力极限状态下主梁配筋计算、正常使用极限状态下裂缝宽度及挠度验算,行车道板计算,横梁计算,支座计算和下部结构计算。设计中用到了工具,通过这次设计也让我熟练的应用CAD,WORD,等软件。本次设计全部按照相应的规范编写,平面图为手绘图,其余图均为电脑出图。关键词:上部结构设计,配筋,验算,下部结构设计ABSTRACTThisdesignf
