Abstract

Abstract

This paper based on shenyang subway project. Conceiving the weekend interval period metro tunnel construction as the background and the application of FLAC numerical simulation analysis software. According to the geological conditions, various of shenyang excavation method applicable range and characteristics of main adopts full section method, double meshshotereting firstly method, retain earth steps method are simulated and analyzed in three ways. and also according to the monitoring displacement, the surrounding elastic-plastic state, anchor axial force and lining of internal rationality of such excavation methods.
- numerical simulation,
- excavation way,
- optimization analysis
