一、设置基线的重要性既有线车站基线的设置,其重要性在于; 1.准确测量股道,道岔、站内建筑物及设备的平面位置。 2.当站场测绘宽度过大,车站中的布置分散时,应以设置的基线为基准,根据需要设置若干个辅助基线,并应联测,构成基线网。 3.在车站的改建工程施工设计中,增建的股道、道岔以及和限界有关的站内建筑物和设备,是以测量的基线为轴线,计算其座标位置。
First, the importance of setting the baseline Existing stations set the baseline line, its importance lies in; 1. Accurate measurement of shares Road, turnouts, station buildings and equipment in the plane position. 2. When depot mapping width is too large, the station layout is scattered, the baseline should be set as a benchmark, according to the need to set up a number of auxiliary baseline, and should be measured together to form the baseline network. 3. In the construction of the reconstruction project of the station, the additional roads, turnouts and station structures and equipment related to the boundaries are calculated based on the measured baseline and the coordinate position.
