Along with fast development of the high speed railway in the our country, More and more high speed track threw in the usage. From the usage circumstance of the foreign high speed track, Occasionally take place the rail to break, Result in very serious danger to the usage of the railway. Traditional solution for rail breaks have already can't satisfy the request of the high speed railway.Therefore.It is necessity that researching the treatment measures for broken rails in the high speed railways,Through the analysis of our country's traditional treatment measures for broken rails under the rapid development of high speed railway, and in combination with specific situation of high speed railway, the paper discusses on the application and problems of traditional treatment measures and recommended on necessary improvements. In the analysis of impact of traditional treatment measures to stress-free temperature, the method of modelling is applied to carry out simulation calculation of the change of longitudinal stress of rails during the traditional treatment process. After studying of adopting the machine to pull to stretch the steel rail. Including some decisive problems within applications, which facilitates the selection of treatment method for damaged and broken high speed track..The research suggests that the traditional way hard satisfy the request in two aspects, Fist after temporary treatment existed joint, Hard satisfy the request of the going smoothly of the high speed railway;Then hard prevent from the change of the stress-free temperature. Therefore, The treatment measures for broken rails in the high speed railway, suggest to adopt new ways, This kind of way is divided into two steps, urgent treatment measures ------Permanent treatment measures. It is good to resolve the problem thatAdopting this reatment method for broken high speed track .
