Abstract:
The stabilities of surrounding rock and tunnel face are estimated by advance geological forecast, monitoring and measuring and stress and strain test; and then the surrounding rock selfstability is improved by advanced support and low prestressed explosion anchor bolt; finally, the large crosssection method with conventional mechanized support is used, the crown top settlement, surrounding convergence and stress and strain are monitored, and the monitoring data are analyzed, so as to improve the safe and rapid construction of weak surrounding rock tunnel. The study results show that: (1) The technologies used can shorten the construction schedule and guarantee the construction safety. (2) Informatized management can guide the field construction by data analysis results, which can greatly improve the management level of tunnel construction.
Key words: ZhengzhouWanzhou highspeed railway tunnel, weak surrounding rock, advance geological forecast, stability of excavation face, conventional mechanized support, large crosssection excavation
