Tunnels of new across the old one with short distance is the emphasis and difficulty in metro engineering development, which has great research values. According to the characteristic of deformation on overlap tunnels with short distance, we put forward the calculating model of lining deformation and internal force analysis. And deduced the formula of calculation on the new tunnel's construction to adjacent ones, then discussed and analyzed the settlement of the point of inflection on soffit lining and the greatest subsidence angle. We verify the theoretical formula about the reliability of the computation and rationality through a series of numerical simulation test against the background of Qingdao overlap tunnels.
