预应力混凝土简支T型梁桥设计.doc

大连星海大桥预应力混凝土简支T型梁桥设计摘要桥是跨越障碍的通道，随着我国城市建设和高等级公路、道路建设的发展，桥梁的建设也将成为必然的趋势。预应力混凝土简支T型梁桥设计在我国公路上修建很多。本毕业设计内容为预应力混凝土简支T型梁桥设计，结构设计包括对预应力混凝土简支T型梁、墩柱及盖梁的设计和计算，具体计算方法包括荷载横向分布系数计算法、容许应力法。施工组织包括钻孔桩施工、T型梁的预制和架设、支座和伸缩缝施工、以及桥面铺装和栏杆施工以及附属结构的施工等。设计中参考了《桥梁计算示例集—混凝土简支梁（板）桥》、《公路钢筋混凝土及预应力桥涵设计规范》、《公路桥涵设计通用规范》、《桥梁工程》、《桥梁施工组织管理》等课内外有关资料。关键词：桥梁，设计，预应力，混凝土T梁AbstractBridgeacrossobstaclescorridors,withoururbanconstructionandthehigh-gradehighway,roadconstruction,bridgebuildingwillalsobecometheinevitabletrend.Pre-stressedConcreteTbridgedesignteamsintheconstructionofmanyofourroads.ThedesignelementsforPre-stressedConcretegraduatedfromTbridgedesign,structuraldesign,includingextensionsofPre-stressedConcrete,andculvertdesignandcalculation,thespecificmethodologyincludinghorizontaldistributionofloadfactorcalculations,allowingstresslaw.Constructionorganizations,includingboredpileconstruction,anderectionofprefabricatedTbridgedesign,secureandjointsconstruction,deckingandrailingsanddeckconstructionandconstructionsubsidiarystructure.Specificreferenceinthedesignofthe"bridgeofexamplesCollection-concreteextensions(board)Bridge,"and"Highwaydesignofreinforcedconcreteandpre-stressednorms","roadtunnelsdesignedgenericnorms","bridgeproject","bridgeconstructionorganizationandmanagement"classesandoutsideinformation.Keywords:bridge，design，pre-stress，concrete，Tbridge目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc233517075"摘要PAGEREF_Toc233517075\hIHYPERLINK\l"_Toc233517076"AbstractⅡHYPERLINK\l"_Toc233517078"一绪论PAGEREF_Toc233517078\h1HYPERLINK\l"_Toc233517079"二方案比选PAGEREF_Toc233517079\h3HYPERLINK\l"_Toc233517080"2.1方案编制PAGEREF_Toc233517080\h3HYPERLINK\l"_Toc233517081"2.2推荐方案PAGEREF_Toc233517081\h4HYPERLINK\l"_Toc233517082"三上部结构设计PAGEREF_Toc233517082\h5HYPERLINK\l"_Toc233517083"3.1设计资料及构造布置PAGEREF_Toc233517083\h5HYPERLINK\l"_Toc233517084"3.1.1设计资料PAGEREF_Toc233517084\h5HYPERLINK\l"_Toc233517085"3.1.2横截面布置PAGEREF_Toc233517085\h7HYPERLINK\l"_Toc233517090"3.1.3横截面沿跨长的变化PAGEREF_T
