【Abstract】 Based on the contact problem model of multilayer thick cylinder of elastic theory,this paper established the stress computation method of lining fracture model on high pressure tunnel of hydraulic engineering and put forword the relevent computation formula of stress exact solution.At last,it adopted the fracture mechanics to analyze the restricted fissure mechanism of steel bar and put forword the calculation method of reinforcement according to the fissure propagated depth allowance.更多还原
