摘要
青岛地铁1号线是国内首条跨海地铁线路,全长59.9 km,其中过海隧道区间长达8.1 km。为充分保证与已建及规划中的地铁线路衔接,提出以QDCORS作为GNSS控制网的起算基准,将Gamit与LGO两种软件解算的基线分别定权,改进了平差算法,优化精密导线网布设方案,保证地面有两个起算方向传入地下,并将测量机器人用于导线外业观测,利用VC6.0开发平台研发边长改化软件,实现边长改正自动化批量处理。
Qingdao Metro Line 1 is China＇s first cross sea subway lines,a total length of 59.9 kilometers,the sea tunnel length of 8.1 km.In order to fully guarantee the cohesion with built and planning subway lines,put forward using QDCORS as the Metro Line 1 GNSS benchmark control network.Using GAMIT and LGO two software to calculate the baseline and weighted adjustment.Improving adjustment algorithm,optimization of precision wire layout,ensure the floor has two from the direction of incoming underground,and measuring robot for wire field observation,using the VC6.0 platform to develop length correction software,realize the change and elevation naturalization automated batch processing of Gauss projection.
