Abstract The potential collapse deformation of loess surrounding tunnel may cause adverse effects on the safety and stability of structure of tunnel. The problem was thus studied in depth with a field immersion test conducted on a construction site of a loess tunnel. The infiltration and collapse deformation of the loess ground and the variation of the mechanical behavior of tunnel structure were the focus of research. The test results showed that the depth of water infiltration in this site was much deeper than that in the natural loess site and the settlement of deep loess was more significant after soaking due to the tunnel excavation. When the water infiltrated into the depth close to the tunnel，the pressure of surrounding soil and the compressive stress at base increased significantly and the stress concentration in the arch springing formed which resulted in the subsidence of tunnel structure. While the settlement in the middle of inverted arch was restrained by the elastic resistance of foundation，and a longitudinal crack formed in the inverted arch because of the differential settlement between the arch springing and the middle of inverted arch. Therefore，for the loess tunnel buried shallow，long-term immersion should be prevented and the bearing capacity of arch springing foundation must be fully considered in the process of design and construction.
