摘要

Considering the interaction between the lining and soil, the analytic solutions to the stress function for the soil and lining deformation caused by the excavation are put forward for the shallow and deep tunnels. The applicability of the algorithm for the shallow and deep tunnels is verified by field monitoring data. Furthermore, through the parameter analysis, a comparison study on the variation of the soil and lining response caused by the excavation for the shallow and deep tunnels is conducted. It is observed that for the soil settlement trough with the value of zero, it is a “groove type” for the shallow tunnel, while “horizontal line” for the deep tunnel. The soil horizontal displacement is “butterfly type” for both shallow and deep tunnels. The lining tangential displacement for the shallow tunnel is an “oblique 8-type” with a smaller bottom, while that for the deep tunnel is a normal “oblique 8-type”.
