In practical engineering, it is often necessary to constructed deep pits next tunnels. So crucial evaluate surrounding tunnels deformation and stress ensure their safe operation. Pasternak soil model that considers nonlinear adopted solve tunnel beam’s differential equation obtain longitudinal stress. The rationality of considering methods was verified by contrasting measured with calculated results. On this basis, a comparative study conducted on the calculation analysis various influencing factors based engineering examples. It shows reduces increase modulus, axis pit long side angle, stiffness reduction coefficient, center horizontal distance. When discrete length less than 5 m, value changes little length. depth increases, maximum also increases gradually. buried gradually in range 1.5~3.9 times depth, rate becomes small. Similar pro-jects construction can refer results, have certain application engineering.
