碩士 === 國立臺灣海洋大學 === 河海工程學系 === 94 === Abstract The goal of already moving towards and " saving effort and melting " gradually so far through the development of the long-term in track engineering and " high strength " advances , there is not a track of cutting that can accord with above-mentioned demands most as for track modelling , but can only adopt on Yu Xin's track of building , still have more than more than 2000 kilometers track that cuts the track for the stone in the route of opening of a iron, if it is extremely difficult to want to reconstruct into and have no one to cut the track and give consideration to the train and operate, so improve the existing intensity of cutting the track of stone and make it save effort and melt to the goal making great efforts for the affair colleague of the worker actively. Generally speaking lay and weld the rail long on the track , can improve the intensity of track effectively and reduce and maintain the worker rate by a wide margin , but lay long and weld the rail and frustrate the stress of the song greatly because of the track so consider horizontal obstruction primarily it is enough. The horizontal obstruction of the track is not unalterable, influenced by a great deal of factors , such as material , weight , size , disposing the interval and a material and volume cut of the sleeper ,etc., is it is it pass through time , train ton count , track maintenance work ,etc. complicated factor to lay to have still while being other, so even the same track that construct, obstruction may not the same either, though sets of iron long to weld to is it accumulate experience that have decades already to lay rail, but cut horizontal obstruction and has not done intact laying testing and quantity to examine to one of various kinds of track states yet, and long to weld rail it lays to be on-line on sharp way of curve (600 of radius under ) never even more. Moreover it is on-line that the railway chief welds the rail construction norm and already allows to long weld the rail and lay in the little radius song of more than 300 metres in radius since revising in 91, but must possess the horizontal obstruction stipulated . Still there are 72 on-line small radius curves among 30000 metres of radius of curve on the line of Yilan of Railway Bureau, for cooperate with manpower simplify policy is it maintain worker rate and cost to reduce , small radius being curve long to weld rail one simple and direct method most in fact, but the small radius curve is frustrated stress of the song bigger than the highway section of the straight line by it under the long vertical axle strength function of rail , how to promote one to cut horizontal obstruction and regard reaching and laying the long demand of welding rail this test as and discuss topics.
