摘　　要：由于自然界中温度的变化、混凝土的收缩和徐变以及各种荷载等因素,桥梁的端部会产生变位,此外,墩、台的自然沉降和位移、各种不可抗力(如地震)的破坏以及纵坡等也会导致桥梁的变位,而正确的伸缩量计算和合理设置伸缩装置可以减小这些变位,论文对中小桥梁伸缩缝的计算和合理设置进行分析。Due to the changes of factors, such as nature temperature change, shrinkage and creep of concrete and various loads, the end of the bridge will produce some changes, in addition, natural settlement and displacement of pier and abutment, force najeure （such as earthquake） damage and slope will also cause the bridge displacement, correct expansion calculation and reasonable expansion device can reduce the displacement, the calculation and reasonable setting of small and medium-sized bridge expansion joint is analyzed.
