Research conclusions；(1) The surface subsidence calculated by Peck Formula is consistent with the actual situation, so Peck Formula has better applicability in Wuhan. (2) Damage level of the building caused by tunnel construction mainly depends on the buried depth of the tunnel, the distance of building to the tunnel and strata loss caused by the construction. The less buried depth of the tunnel and the less distance of building to the tunnel cause larger loss of strata, resulting in larger deformations of surface and building. (3) Damage levels of the buildings caused by tunnel construction can be divided into five categories. To the I and E extent affected buildings, it does not need to take the measures for protection and treatment. To the extent IH - V extent buildings, it must take effective measures for protection.
