The formulation of bolt axis-stress and deformation according to common transmutation principle in elasticity mechanics is deduced, which is fully considered under the condition of correspond transmutation of bolt, serosity and rock. Simultaneously, the formulation is applied to analyze the results of in-situ experimentation at Jiehe intersection bridge on 104 national road, it certificated that the compute method men-tional above is credible in reason and it will be used in other engineering cases.
