| Abstract: | Introduces the basic principle of the optimal design of roadway supporting system in soft rocks based on reliability and gives the establish ment of a modal of the structural optimization design. This paper analyzes and predicts remodeling cost by BP neural network, and gives the discussion on optimal design by releasing the restriction method and the target reliability performance-based of supporting system. The optimum designing method is used to analyse the reliability in the supporting discussion of S2S10 convergence in roadway, and gives the discussion on optimal design of the combined supporting system in life cycle. |
