Analysis on Surrounding Rock Deformation of Shallowly-Buried Portal Part of Double-Line Tunnel

Abstract:

Through studying the ground surface settlement monitoring for Fang Dou Shan highway tunnel Shallowly-buried Portal Part, this paper mainly discusses the deformation of surrounding rock range from ground surface to the arch crown of double-line tunnel, and analyses the effect on stability of surrounding rock during construction, with the whole process of excavation of highway tunnel being simulated by FLAC_3D. It can make great significance for construction safety and some other related parts.
