摘　　要：对桥墩纵向线刚度限值的合理性、无缝线路纵向力的荷载组合等关键技术问题进行了深入的探讨,对桥上无缝线路的设计有一定的参考价值。This paper makes a deep-going study of several key technical issues, such as the rationality of the limit values of longitudinal linear rigidity of bridge piers and the load combina- tions of longitudinal forces of jointless tracks used on bridge deck. The study in the paper is of certain reference to the design of the jointless tracks.

关 键 词：桥梁 无缝线路 线刚度 荷截组合 探讨
