摘　　要：随着城市化的进程逐步加快,城市建设与城市发展对城市交通的要求日益增高,跨越式的建筑逐渐增多。市政桥梁在材料性质、行车荷载和环境温度的作用下出现收缩和膨胀的现象,因此,为了保证市政桥梁的安全和结构稳定,在桥梁施工过程中都会设置设置伸缩缝。以市政桥梁伸缩缝的类型为切入点,对市政桥梁伸缩缝施工技术的应用要点进行探析。In the process of urbanization gradually accelerated, urban construction and urban development of the requirements of urban traffic is increasing, and the construction of the building is increasing.Municipal Bridge in material properties, traffic load and environment temperature effect appeared contraction and expansion of the phenomenon.Therefore, in order to ensure that the municipal bridge safety and structural stability, in the construction process of the bridge will set expansion joints.The author takes the type of municipal bridge expansion joint as the breakthrough point, and analyzes the application of the construction technology of the municipal bridge expansion joint.
