摘　　要：沿海某城市快速路上的一座跨线桥为了解决伸缩装置破损和桥头跳车等问题采用了整体式无缝桥结构。论文以其为工程背景,利用Midas Civil软件建立全桥杆系有限元模型,简要探讨了整体式无缝桥梁在模型建立时主要参数的输入、桩-土作用的模拟需要注意的一些问题,概括了整体式无缝桥的设计要点,也给出了一些构造设计的建议,为整体式无缝桥梁的应用提供参考。In order to solve the problems ofexpansion joint damage and vehiclejolting at bridgehead,an integral abutment jointless bridge was adopted for a span bridge on the expressway in a coastal city.Based on the engineering background,this paper uses Midas Civil software to establish the finite element model of the whole bridge rod system.This paper briefly discusses the input of main parameters and some problems needing attention in the simulation of pile-soil interaction during the model establishment of integral seamless bridge,and summarizes the design key points of integral seamless bridge.And some suggestions on structural design are also given to provide reference for the practical application of integral seamless bridge.
