普铁隧道无砟轨道精密控制网技术研究

Research on Precision Control Network of Ballastless Track of Putie Tunnel

普铁长大隧道通常会铺设无砟轨道,而保障无砟轨道的精确性是普通铁路隧道工程得以保质保量完成的关键所在。在这一背景下,对普通铁路隧道无砟轨道测量的内容与流程进行论述,着重围绕普通铁路隧道无砟轨道精密控制网技术进行简要分析研究。

The ballastless track is usually laid in the long long tunnel, and the accuracy of ballastless track is the key to the completion of the quality and quality of the ordinary railway tunnel. Under this background, this paper discusses the content and process of ballastless track measurement in ordinary railway tunnel, and focuses on the brief analysis and Research on the precision control network technology of ballastless track in ordinary railway tunnel.
