摘　　要："三无曲线"作为铁路曲线中的一类较为特殊的曲线,其拨道问题一直困扰着我们铁路工务的一线工作者们。后来绳正法对这一问题给出了很好的解决办法。但在使用绳正法拨道时一条必须满足的条件就是:实量正矢的合计必须要与计划正矢的合计相等,但在我们的现场工作中会发现满足这一条件极为困难。本文主要针对速度在120km/h以下的普通线路在实量正矢合计与计划正矢合计不等但误差不是很大时的"三无曲线"拨道提出解决办法。具体做法是在除了0点以外的每一个点上加上或减去相等数值使得实量正矢合计与计划正矢合计相等,然后套用绳正法算法进行拨道。最大误差为多少将在下文中具体介绍。＇Sanwu＇ curve is regarded as a special curve among many kinds of railways. We were confused about the adjustment of its shape at the beginning. There are a method which can be used to solve this problem. But the only condition that musted be satisfied is that the sum of the total actual versin must be equal to the total theoretical versin.but actually, we found it＇s very difficult to satisfy the condition, this passage is to supply a method for the situation where the train speed is not beyong 120 kilometers per hour and the deviation between the total actual versin and the total theoretical versin is not very obvious, the particular method is to minus or plus a value that is equal to itselves＇ value at every point except for the point the value of which is equal to zero, you can correct railway after the total actual versin is equal to the total theoretical one. how the the maximum deviation is like will be introduced in the following.
