Abstract: Based on engineering geological features of tunnel setting, a1:1 hypostatic model of Tong-Yu deep buried highway tunnel is built. Combined measuring results, characteristics of yield degree, displacement, stress of surrounding rock-supports structure, as well as steel support force and lining axis force and bending moment of supports structure are analysed when the tunnel adopting full face method and bench method dynamic excavation. The analytical results show that the bench method there isn’t obvious advantage than full face method. The study provides a scientific basis for optimizing design and construction of deep buried highway tunnels.

Key words: deep buried tunnel, surrounding rock-supports structure (SRSS), displacement, stress, numerical modeling
