高净空隧道刚性接触网横向测量方法探讨

Discussion of Methods for Transverse Measurement of Rigid Suspension of Overhead Contact System in High Headroom Tunnel

阐述了高净空(h>4 800 mm)隧道刚性接触网横向测量在直线区段和曲线区段不同位置所采用的不同测量方法,并得出了曲线段偏移调整距离计算式。

The paper illustrates different methods for transverse measurement of rigid suspension of overhead contact system in high headroom tunnel （h〉4 800 mm） adopted separately at straight line section and curve section, and the calculation formula for computation of offset adjustment distance at curve section is obtained accordingly .
