Abstract:

Based on principle of initial parameter method, the initial parameter matrix equation of force and displacement of circular beam on elastic foundation if established. Then, the matrix equation and some structure characters, including structure symmetry, force balance and displacement compatibility, are used to achieve initial parameter values for multi-center circular tunnel lining. As a result, force and displacement of every point on circular arc could be obtained. Finally, the result of case calculation indicates that the method proposed is feasible and effective. Meanwhile, the method could be considered as another approach of internal force analysis for tunnel design.

Key words: initial parameter method, multi-center circular arc tunnel lining, circular beam on elastic foundation, internal force and displacement.
