摘　　要：在高速公路放线竖曲线的计算中,以往均采用计算器逐点计算其设计高程,这种方法不仅效率低,且极易出错。为解决此问题,利用VB编程方法,将事先标记的点位通过全站仪导入计算机并利用VB编写好的程序,对所有点位进行设计高程一次性导入批量计算。该法可在高速公路施工测量中对任意层面,任意中桩、边桩,以及任意点的设计高程进行批量计算,运用简便、计算精准,不仅大大提高了工作效率,而且减少了错误发生的机率。In the calculation of vertical curve in the setting out for expressway, the designed elevation was calculated using calculator point by point, which was low - efficiency and error - prone. To solve this problem, the previously labeled point data can be imported into computer using Total Station, then, using VB program to conduct batch computing of all the designed elevation. In the construction survey of expressway, the designed elevation of any bedding, any middle pile and side pile , any point can be calculated in a batch using this method. The method is convenient and accurate, which improves engineering efficiency and minimizes the chance of errors.
