【摘要】 <正> 一、前言 哈尔滨松花江公路大桥是我国公路建设的特大桥梁,全长1656m,其中主桥748m(59+7×90+59m),为九跨预应力混凝土连续箱梁,横截面采用矩形双箱、行车道宽19m、两侧人行道各宽2.5m、采用分箱悬浇,连成整体的施工方案。设计荷载为汽车超-20级,验算荷载挂-120。该桥设计计算时将二个分离的单箱简化为I形梁,引用荷载横向分布系数2.4,按平面杆系进行电算。我们受大桥指挥部的委托进行结构模型更多还原

【Abstract】 A research project was carried by means ot a motet test to investigate the coefficient of load transverse distribution in multiple-span prestressed continuous box beam and the stress in the main sections. A dicussion of the influence of the number of diaphragms on thestructure is also given in this paper. It supplies the scientific data for the later design of similar bridges and is also benefit to the Harbin Songhuajiang Highway Bridge which is under construction.更多还原
