The Technical Of Tunnel Monitoring Measurement Applied In The Yingzuishan Tunnel

With the rapid development of economy, there are many tunnels on the traffic line. How to eusure the stability of surrounding rock and supporting structure in the different geological conditions, detection and measurement are a key proess.In the paper, construction measurement technology on NATM is discussed in detail and methods of measurement data processing are researched exploratorily. The study has not onlv theoretical value, but also imnortant engineering sense as well. The contents in this paper are concluded as follows:1.Based on the research output of predecessor, in this paper, the mechanics of tunnel excavation and supporting structure and the relationship of among advanced support, primary support, secondary lining and stability of surrounding rock are studied;2.Content of detection and measurement, and method of measurement data analysis and processing are discussed in idea of dynamic construction;3.Yinzuishan tunnel has complex engineering environment, construction method is determined considering various unfavorable factors. By the observation of inner tunnel, geological forecast, and displacement measurement,the stability of the surrounding rock and supporting structure is eusured.
