摘要
本文以南京地铁一号线盾构三标(玄武门至南京站)为例,分析了线路中桩坐标计算程序的编写思路,阐述了根据里程(桩号)求坐标的方法。用计算机对隧道中心与线路中心坐标进行了计算,克服了手工计算缓和曲线及隧道中心与线路中心的偏移量上的繁杂。简化了工作量,保证了测量数据处理的准确与快速。
Based on Xuannan part of Nanjing subway line one, the paper analyzes the steps of programming for Central Coordinate of Subway Tunnel, and discusses the method of computing coordinate values in mileage. The computer program overcomes the complication of manual computing transition curve and deviation value between tunnel center and line center, also reduces the amount of work, and ensures the accuracy and high speed of processing measured data.
