| 摘 要： | 为了研究过桥管线对桥梁工作性能的影响程度,以温州市大门大桥工程引桥(连续箱梁桥)为工程背景,通过对管线布置方案的比选,确定该桥采用桥面两侧“管线专用区域”的布置方案；并就输水管道对桥梁结构的影响进行静、动力分析研究.研究表明,水荷载引起的桥梁跨中挠度与荷载短期效应组合下跨中挠度相比,可以忽略；连续梁结构的固有频率与输水管道内恒定流频率的波动范围不同,二者不会产生共振现象；水荷载引起的桥梁结构正截面应力增量小于1 MPa,不足以影响桥梁的安全运营.

| Abstract: | To study the degree of the influence of pipelines across bridge on the working performance of the bridge itself,the approach bridge(a continuous box girder bridge) of the Damen Bridge in Wenzhou City was cited as an example.On the basis of comparison of the different pipeline layout schemes,it was determined that the layout scheme of special zones for the pipelines on both sides of the deck of the bridge should be adopted and the dynamic and static force analysis and study were made for the influence of the... |
