摘　　要：基于偏角法的曲线放样数据计算过程繁琐,且传统的手工计算方法易受人为因素影响,当放样数据量过大时,极易出现错误,会给实际生产带来损失。针对此问题,文章编写了一个基于C++与Qt的曲线放样数据自动计算程序。利用该程序可以快速、准确实现圆曲线与缓和曲线上整桩里程编号、桩间间距和偏角值的自动计算,并对计算结果进行保存,为后续工程实际放样提供可靠数据。通过对缓和曲线进行实验,结果表明该程序可以快速准确计算放样的相关数据,并对其进行保存,在实际生产中使用该程序计算放样数据,可提高工作效率,具有一定的应用价值。The calculation process of curve lofting data based on deflecting angle method is tedious,and the traditional manual method is easily influenced by human factors.When the data is very large,it is easy to make mistakes in the process of calculation and result in making loss in practice.In order to solve the problems mentioned above,an automatic calculation program of curve lofting based on C++and Qt is proposed in this paper.The program can quickly and accurately realize the automatic calculation of the whole pile mileage number,distance between adjacent pile mileages and deflection angle value in the circular and mitigation curve,which can provide the reliable data for practical lofting.Experiment on the mitigation curve is conducted and the results show that the program can quickly and accurately calculate the lofting data and save the relevant data.The work efficiency can be greatly improved by using the proposed program,and the program can make certain application value.
