高速铁路超长越岭隧道GPS洞外控制测量方案研究

Controlling survey scheme of GPS in long tunnel for the high-speed railways

随着国内多条新建铁路客运专线的开工建设,山区10km以上长大越岭铁路隧道项目显著增多,为了确保隧道贯通误差符合相关规范要求,需要做好隧道洞外GPS控制测量技术方案设计和测量工作。本文以南梁-太行山超长隧道为例,研究利用GPS精密控制测量方法对隧道进行独立控制以确保隧道正确贯通。

Some passenger-dedicated railways have been constructed in our country, and some long tunnels have been designed in these engineering, especially in western China＇s mountain areas, for decrease the projective distortion of these new lines. This paper has used GPS precise control survey in tunnels separately to make sure the perforation of them.
