在铁路工务部门,经常遇到曲线整正计算。整正曲线的计算方法有多种,角图法就是其中重要的一种。该方法优点是:外业工作量小,计算精度高,对恢复和改善曲线的圆顺度,提高线路质量,保证行车安全起重要作用。尤其在线路大修设计、旧线测量中大量采 In the railway construction department, often encounter curve correction. There are many ways to calculate the orthorectified curve, and the angle map method is one of the important ones. The method has the advantages of small working load and high calculation precision, playing an important role in restoring and improving the roundness of the curve, improving the line quality and ensuring traffic safety. Especially in the line overhaul design, a lot of mining in the old line measurement
