Earth pressure prediction based on anfis for earth pressure balance shields

During the tunneling process of the earth pressure balance shield machine, the tunnel face stability must be guaranteed to avoid the ground settlement and ensure safe construction. In order to stabilize the tunnel face and obtain the optimal control parameters of the EPB shield machine, it is very necessary to predict the earth pressure in the chamber. In this paper, an earth pressure prediction model is constructed to predict the earth pressure at the next moment by using the adaptive network-based fuzzy inference system, based on the mechanism analysis of the earth pressure. The experimental results show that our method has higher prediction accuracy than BP algorithm and is very effective to predict the earth pressure in the chamber.
