黄土地区盾构始发监控测量方法研究分析

盾构始发是指盾构从组装调试到盾构完全进入区间隧道,并完成始发掘进为止的一系列施工过程,黄土地区盾构施工尤其要求主要盾构始发阶段的施工监测要求和测量方法。文章结合西安铁路六号线监控测量方法,来分析黄土地区盾构始发在中线测量,姿态测量,盾构推进测量等方面的问题,通过本工程的深入研究,为类型工程施工提供有效的借鉴经验。

Shield starting refers to a series of construction process from assembling and debugging to fully entering the interval tunnel and completing the initial tunneling. In the loess area shield construction especially requires the construction monitoring re-quirements and measurement methods of the main shield construction stage. Adopting the monitoring and surveying method of Xi＇an Railway Line 6, this paper analyzes the problems of shield tunneling in the middle line, attitude measurement, shield propulsion sur- vey and so on in loess area, and through the in-depth study of this project, it is to provide effective reference experience for thetype of engineering construction.
