摘　　要： 分析了水泥混凝土路面传荷系统在重复荷载下的工作机理，建立并验证了在重复荷载下水泥混凝土路面传力杆接缝力学模型，并将其应用于有限元计算中．明确了使用过程中接缝处荷载弯沉关系，指出接缝松动累积是造成这种关系的根本原因． Performance analysis of doweled joints under repetitive loading is presented. A new model of doweled joints under repetitive loading is formed and verified and is used in finite element analysis. Through the study, the relationship between load and deflection nearby the joints is established when the pavement is in use. The study proves that the accumulation of dowel looseness is the main factor which causes this special relation. The application of the model is also discussed.
