截至2014年年底，我国公路桥梁总数已达75.71万座，4257.89万延米i。

进百万的桥梁屹立在我国交通线上，其安全便是头等大事。

随着交通运输线的再扩大，连续刚构桥跨越能力大，施工难度小，行车舒顺，养护简便，造价较低等优点将被广泛应用。

二、工程模型：现有某预应力混凝土连续刚构桥，桥梁全长为184m，宽13m，其中车行道宽11.5m，两侧防撞栏杆各0.75m主梁采用C50混凝土。

桥梁设计载荷为公路—— 级。

图2-1桥梁侧立面图上部结构为48m+88m+48m三跨预应力混凝土边界面连续箱梁。

箱梁为单箱双室箱形截面，箱梁根部高5m，中跨梁高2.2m，边跨梁端高2.2m。

箱梁顶板宽12.7m,底板宽8.7m,翼缘板悬臂长2.0m，箱梁高度从距墩中心3.0m处到跨中合龙段处按二次抛物线变化。

0号至3号块长3m（4x3m)，4、5号块长3.5m(2x3.5m)，6号块到合龙段长4m(6x4m)，合龙段长2m。

边跨端部设1.5m横隔板，墩顶0号块设两道厚1.2m横隔板。

0号块范围内箱梁底板厚度为0.90m，1号块范围内底板厚度由0.90m线性变化到0.557m，2号块到合龙段范围内底板厚度由0.557m 线性变化到0.3m。

ansys桥梁模型建立

在桥梁用ansys建立模型时，可参照以下建议的单元进行桥桑模型的建立.L梁（配筋）单元：桥墩.箱梁、纵横梁°2、板无（配筋）单元：桥面系烧。

3、冥体（配筋）单元：桥議系烧、基础结构。

4、拉杆单元：拱桥的系杆、吊杆.5、拉寒单元：斜拉桥的寒、想索桥的钢丝龜。

6、演紧单元：察力控制、螺栓柳钉楚接.7、连接单元：支座、堆基。

连接部分解决方法：ansys在解决桥梁不同的连楼部位时可遶用如下的方法：1、C ombin7. Co<nbin40. LinklL Combin52. Ccnbin38禅簧（阻尼、问陳元）：可爲来模拟支座、媚瓠拉杆等桥梁部使。

2、艮紧单元可解决螺栓、紳钉连楼的问題&3、二力杆拉杆、索可解决拉索问题.4、锅合与约束方稚可解决梁与塔横梁的边界妁束关系。

5、接触单元如Contiwtl52可模拟•滑动支座、销接等需件的真冥情况。

常见桥梁發触问題：U淸动苣接：点点接離2、绑走這接：点面接触3、辕动匹接：面面接触基础的处理方式：U基础平台与桩基：用实体模型、预应力配筋2、基础与岩土系统：祢限区域实体模型、预应力配筋桥梁中常见的模型可以用相应的草元1、刚构桥.拱桥：梁与杆单元姐合模型2、钢管跄：复合竄面梁模型3、连续梁：梁模型4、料拉桥.患既桥：梁、板売、裳或杆单元绘合模型5、立交桥：娈体墩、板无桥面和加强梁混合模型6、局篩详纽计算：实体（考虑配筋〉或板模型，以便考虑模型细节符征.如结构尺寸构造側角、厚薄或粗细过度、凹凸却其配筋k.9.-70/prep7 et. l.beiiml et.2 JinklOet.3.shell63r.1.2...1.2r.2. •mp.ex.1.2ellmp.nuxy ・l ・mp.dens.1.7800 mp.ex.2.3el0mp ・nuxy ・2・ mp.dens.2.3000 k.l.-60. 10.0k.2.-50k.3.-30.15k.4.-10.20k.5.10.20k.6.30.15k.7.50k.8.60.-10k ・10.・60k.11,-30 k.12,-10k.13,10k. 11.30k.15.60k. 16,70kgen,2.all .......... -20. .0 ♦do.i.1.7l.i.inl.i+16.iH7拿enddo拿do.i・2・7l.i.i416拿enddo1.L91.1,101.17.251.17.261.8.151.8.161.24.311.24.321.2.171.8.231.7.24拿do.i.3.6l.i+16.i*24♦enddo<1.9.10.26.25a.10,2.18.26a.2.11.27.18a.llJ2.28.27a.12,13.29.28 aJ3J4.30.29a. 14,7.23.30a.7.15.31.23a.15,16.32.31 !桥体權粟lsel.s...1.32 latt,1.1.1 1esize・nl1.2 lmesh.all!悬索lsel.s...33.40Imesh.all!桥面aatt.2.3.3aesize.nl1.2 amesh.all。
