摘　　要：城市桥梁常用的桥台型式有重力式桥台、轻型桥台、肋板式桥台等,这些常用的桥台均需大开挖,影响范围大,建设工期长,排桩式桥台正好能弥补传统常用桥台的这些缺点,介绍了排桩式桥台的构造及计算过程,结合某桥梁工程应用实例,经过2年通车运营,应用效果良好,值得在城市新建及改造桥梁工程中应用与推广。The commonly-used abutment types of urban bridges include gravity abutment,light-weight abutment,rib slab abutment andso on.These commonly-used abutments need large excavation,with large scope of influence and long construction period.The row pile abutment can just make up for these shortcomings of the traditional commonly-used abutments.The calculation process of the row pile abutment is introduced.In combination with the engineering application example of a bridge,the application effect is good after two years of traffic operation,and it is worthy of application and promotion in the new construction and reconstruction of urban bridge engineering.
