摘要
本课题的设计为预应力空心板梁桥设计名为熊兔大桥:桥长60m,,桥面宽10m,(人行道)×2 + ×2(车道)。本次设计首先进行方案比选,然后对各位置结构所需要进行设计的荷载进行了计算,及配筋计算和墩柱等设计计算。在计算过程中,对结构内力的结构主要是进行了计算,并且对各位置设计的是否合理进行了验算,充分学****了与桥梁相关的知识。桥梁车道为两车道,设计荷载是公路II级。本桥的预应力空心板配筋采用部分预应力A类截面设计,用先张法施工对桥面施工,选用预应力钢筋,1×7钢绞线,,其余部分普通钢筋采用HRB235或R235。在设计过程中对上部的内力结构可变荷载,恒载及配筋都进行了计算并对其都进行了合理验算。本桥支座由4层钢板和5层橡胶的组成板式橡胶支座,设计部分主要进行支座的偏转及抗滑稳定性的验算,之后我们进行了盖梁,墩柱以及灌注桩的基本设计,内力计算以及合理性验算。
关键词:预应力: 荷载:先张法
Abstracts
This graduation project topic is prestressed concrete hollow slab bridge, it called Xiongtu Bridge. The bridge is 60 meters in length, arranged 6 cross per meters, the width of deck is 10 meters, including meters(sidewalk)×2+×2(carriageway).First,the design is carried out alternatives,then we calculate the position of the load structure,reinforcement calculate,and pier calculate。During the calculate ,we did a lot puting about internal force,and we were checking each position whether it is also learn much knowledge about design is load П grade,and make two lane prestressed hollow reinforcement is class A cross-sectional ,the bridge of construction using the pre-tensioning method and prestressing steel strand is the 1×7 and the diameter is ,the ordinary steel choose HRB235 and the design process,we make the calculate and checking about the upper part of the internal forces’ variable load,dead load and bridge’s bearing choose the steel plate of four-layer ,the rubber of five-layer makes up the laminated rubber bearing,and we check the bearing the stability against sliding bearing make the calculate about capping beam,pier and bored piles of internal force and checking.
Key words: prestress :load :pre-tensioning meth
