The main 2D back analysis model is established considering actual situations of the way the arch ring is set and the composition of its section. After introducing the stress release rate and the load bias parameter to composing the integral equation of the influence value, the data of arch crown settlement and horizontal convergence can be used to back analyse the load status of the supporting structure. By changing the modeling parameters, the optimizing construction scheme can be simulated and the most unfavorable stress value is analyzed, which can provide references to similar engineering.
