Road center line coordinate lofting method
The invention discloses a road center line coordinate lofting method which is used for solving the problems that an existing lofting method is multiple in field operation steps and low in field operation efficiency. The method comprises the following steps: determining a maximum control distance between a lofting point and a measuring station point of a road center line according to a road construction precision requirement and a nominal precision parameter of a total station for lofting; dividing the road center line into a plurality of lofting sections according to the positions of the observation stations and the maximum control distance; before center line lofting operation is carried out, calclulating standard lofting elements based on a preset program according to observation station point coordinates, rear view point coordinates and lofting point coordinates; and according to the standard lofting elements, carrying out center line lofting in the lofting section through lofting equipment. The lofting elements of each lofting point of the road under the conditions of a set observation site and a set rear view point are calculated indoors, and some operations originally needing to be carried out on site are transferred indoors, so that the field operation efficiency can be greatly improved, and the occurrence probability of field errors is reduced.
本申请公开了一种公路中线坐标放样方法，用以解决现有的放样方法外业操作步骤多、外业作业效率低的问题。该方法包括根据公路施工精度要求和用于放样的全站仪的标称精度参数，确定公路中线的放样点和测站点之间的最大控制距离；根据测站点的位置和最大控制距离，将公路中线划分为若干放样区段；进行中线放样作业之前，基于预先设定的程序，根据测站点坐标、后视点坐标和放样点坐标，计算标准放样元素；按照标准放样元素，通过放样设备，在放样区段进行中线放样。通过在室内计算公路的每个放样点在设定的测站点和后视点的条件下的放样元素，将原本需要在现场进行的一些操作转移到室内，可大大提高外业作业效率，减少外业错误出现的几率。
