摘　　要：先简支后连续T梁是国内外高速公路上常用的一种桥梁结构新形式,具有施工简易、行车条件好且经济合理,并兼备简支梁与连续梁桥的优点.以三跨预应力混凝土先简支后连续T梁为例.简要介绍随岳高速公路中广泛采用的先简支后连续梁桥的结构设计特点和计算方法.Continuous simple supported Tshaped girder is a new bridge structure system applied widespread on Freeway at home and abroad, which has the features of simple construction, smooth travel condition and appropriate cost. It has the merits of both simplesupported system and continuous system. Based on a design example of a continuous threespan simple supported Tshaped girder, the structual characteristics and computation method of continuous simple supported girder bridge are introudced, which is applied on Suiyue Freeway.
