摘　　要：本文介绍了一次以“无接头桥梁”为主题的ＩＡＢＳＥ英国分会的学术会议，并由此开始从桥梁连续整体性论述桥上无缝线路的重要意义、西欧无缝线路的技术要求、无缝线路与有缝线路钢轨应力的比较、伸缩长度的计算等问题。本文之后，本刊将继续发表作者题为“西欧铁路桥梁的无缝线路”的后续文章，对桥上无缝线路纵向力计算重点，国际铁路联合组织（ＵＩＣ）对桥上无缝线路的设计原则、西欧桥上无缝线路不设伸缩接头的最大跨度、降低附加力的措施及伸缩接头的新构思等做了介绍。The paper introduces an academic conference convened by the Britain Branch of IABSE.The subject of the conference was named as “Running toward Jointless Bridge.”From that time,based on the integral continuity of bridge,the following problems were discussed:the inportant meaning of jointless rail on bridge,technical requirements of jointless rail in West Europe,comparison of stress between jointless rail and jointed rail calculation of length of rail expansion,ect.Another thesis named as“Jointless Rail on Bridge in Railway of Wast Europe”written by the author will be issued in our peridical hereafter,in which the following articles will be introduced:essentails for calculating the longinudinal force on jointeless rail on bridge,design principle for jointless rail on bridge by UIC,maximum span of bridge having jointless rail on bridge without expasion joints,measures for reducing additional force,new concept on expansion joints etc.
