- Abstract
For the super-large section tunnel due to its super large span and flatness,together with the effect of various processes and excitation of surrounding rock during construction,the mechanical behavior of super-large section tunnel is quite complicated.Making use of the "CTSSSRH",the physical analogue for simulating the construction dynamic process of super-large section tunnel in different construction methods is experimented.The rule of surrounding rock displacement and strain development is studied and the reasonable construction method is put forward.
