Abstract The arch foot with an expansion section can be applied to well control deformation of large-section tunnels built in soft layers. Based on previous researches，the structure of arch foot with an expansion section is further developed，it presents a method designing an anti-slide arch foot in the tunnel. The effects of the large arch foot on the deformation of the strata are studied by theoretical study，numerical calculation and field measurement. Research results show that the anti-slide arch foot in the tunnel is able to control convergence of surrounding rocks of the tunnel effectively，as well as control settlements of vault of the tunnel. It happens mainly because the anti-slide arch foot with an expansion section is inserted into the surrounding rock，which can produce lateral resistance and prevent the arch foot from moving towards the side of tunnel near the air. Furthermore，the research results reveal that the length of the arch foot is related to classification of surrounding rocks considering mechanical behavior of arch foot subjected to forces. Under the same surrounding rocks，the length of arch foot and its ends that inserted into the soil increase nonlinearly if classification of the surrounding rock varies from III to VI.

Key words： tunnelling engineering large section tunnel anti-slide arch foot with an expansion section field tests convergence numerical simulation
