A plan finite element model is established by means of multidisplacement back analysis method, so as to learn the rock stress distribution rules on support structure of shallowcovered unsymmetrically pressured tunnel. Meanwhile, the stress releasing rate, unsymmetrical pressure and influencing value loading principle are adopted in order to obtain formula of rock stress distribution. The comparison between calculated results and measured data shows that the formula and calculated results obtained are feasible and effective. The study results can provide references for similar projects in the future.
