如何保持曲线线形的正确位置,是养路部门多年来一直在进行探索的问题,为此,人们研究了许多曲线整正计算方法;规定了按旬、月的拨道制度,这些措施在提高曲线养护质量方面都起到了一定的作用。但是随着轨道构造的加强和更新,电子计算机等新的技术设备的应用,人们对曲线养护方法的认识,也应该随 How to maintain the correct position of the curvilinear shape is the issue that the maintenance department has been exploring for many years. For this reason, many people have studied many methods for calculating the curvilinear alignment, and have stipulated the ten-day and the forthment system. These measures are of great value in improving curve maintenance Quality has played a role. However, with the strengthening and updating of the orbital structure and the application of new technology and equipment such as electronic computers, people’s understanding of the method of curve maintenance should also be followed
