在测设公路平曲线中，传统的详细测设方法，往往是将仪器安置在已测设好的平曲线要素桩上，采用切线支距法或偏角法进行测设，这种方法，受到地形、地物限制比较大，速度慢，劳动强度大，而且有时精度难以达到要求。为了解决上述问题，提出采用全站式电子速测仪，借助ＰＣ—１６００（或ＰＣ—１５００）袖珍机相配合编写一套测设程序及测设方法，通过几条公路的测设应用表明，不但灵活性大，而且劳动强度大大地降低，速度也相应地加快，精度远远地超过要求。
In measuring the flat curve of the road, the traditional method of measuring and measuring is usually to place the instrument on the measured flat curve element pile, using the tangent offset method or the declination method to measure the position. In this method, Topography, terrain restrictions, slow, labor-intensive, and sometimes difficult to meet the accuracy requirements. In order to solve the above problems, a total station electronic speed measuring instrument is proposed. With the aid of the PC-1600 (or PC-1500) compact machine, a set of measuring and measuring program and measuring method are proposed. By measuring and measuring the application of several highways, Not only flexibility, but also significantly reduce the labor intensity, the corresponding speed up, the accuracy far exceeds the requirements.
