摘　　要：为了解决粤港澳大湾区长带状城际铁路坐标基准投影变形问题,提出了基于北斗卫星导航基准站网的基准建立和施工控制网联动及稳定性评估方法,详细论述了高斯投影长度变形影响及解决方案、工程独立坐标系的建立和维持方法、高程基准的差异解决方案,针对不同地形分别给出了2种解决方案,符合投影变形限差的比例均可以达到89.78%以上,并以南珠中城际铁路为实例,论证了该方法的可行性,为类似长带状交通工程提供技术参考与借鉴。In order to solve the problem of coordinate datum projection deformation of long-strip intercity railway in Guangdong-Hong Kong-Macao Greater Bay Area,a method based on Beidou satellite navigation datum network datum establishment and construction control network linkage and stability assessment is proposed.The influence of Gaussian projection length deformation and its solution,the establishment and maintenance method of independent engineering coordinate system,and the difference solution of elevation datum are discussed in detail.Based on different terrain,two solutions are presented respectively,and the proportion meeting the projection deformation limit can reach more than 89.78%.The feasibility of this method is demonstrated by taking South Zhuhai-Central Intercity Railway as an example,which can provide technical reference for similar long strip traffic projects.
