在线路勘测中,都是现场定线、测距、测角等,一般没有曲线的坐标。这样就无法利用坐标放线法测设曲线,目前在曲线测设时,只能应用切线支距法或偏角法。而该文章“坐标放线法在公路一次定测中的应用”就是充分发挥光电测距仪的测距优势,应用更新换代的坐标放线法测设曲线,收到极好效果。本文重点阐述了: 1.坐标放线法的基本原理和方法; 2.用坐标放线法测定曲线,提高了测设精度和速度; 3.还可以用光电测距仪与钢尺配合使用效果十分可佳。
In the line survey, all are on-site alignment, ranging, angle measurement, etc., generally do not have the coordinates of the curve. This can not use the coordinate line method to measure the curve, the current test set the curve, only the tangent offset method or declination method. The article “coordinate pay-off method in a road to determine the application of” is to give full play to the optical range finder distance measurement advantages, the application of the updated coordinates of the pay-off method to measure the curve, received excellent results. This paper focuses on: 1. Coordinate pay-off method of the basic principles and methods; 2. Coordinate pay-off method to determine the curve to improve the accuracy of measurement and speed; 3. You can also use the optical distance meter with the steel ruler with the effect Very good.
