| 摘 要： | 以回旋线为主的缓和曲线已不能满足高铁提速等要求,许多新的线形被引入工程中,就造成了计算放样数据工作量大且容易出错。开发直观、快速且适应各种缓和曲线的放样程序对加快施工有着重要意义。推导了适用于各种类型缓和曲线的中边桩计算公式,借助ACCESS数据库储存线路信息,提出一种快速反算方法,利用C#语言编程实现适合多种类型的缓和曲线的快速直观放样程序。

| Abstract: | Besides several spiral curves used, some new types of transition curves have been adopted for the smoothness of the high-speed railway. It is difficult and error prone for setting out those transition curves by hand calculator. So it is necessary to develop a software for setting out any types of transition curves accurately and quickly. General numerical models for calculating coordinates of middle stakes are proposed, and all of the information are stored in ACCESS. Adopting an inverse coordinate calculation method, the setting out software which is suitable for any type of transition curves is developed. Comparing with hand calculation method, the software can provide more accurate results with visualized interface. |
