Adopting the adaptive network-based fuzzy inference system,a earth pressure balance(EPB)control model with the real-time measured data of earth pressure,thrust force and thrust speed as three inputs,and the speed of screw conveyor as output was designe.

Theoretical equations by analyzing earth pressure balance(EPB) shield cutterhead′s cutting the ground are deduced and the numerical model is set up.

Analysis of reasonable thrust force during tunnel excavation in homogeneous soft ground by use of earth pressure balance shield machine;

Realization of earth pressure balance for shield tunnelling machine;

Based on the tunnel construction between Gubei Road Station and Zhongshan Park Station, this paper introduces the design and manufactumg techniques, features and application of the frst homemaclc earth pressure balance shield machine in the tunnel construction of metro.

This paper describes a detailed computation of driving torque moment for earth pressure balanced shield under shanghai soft foundation,which analyzes every parts resisting moment based on Rankine theory.

EPB (earth pressure balanced) Shield tunneling method is an effective method in tunneling construction and has the obvious advantage in the aspect of controlling the distortion of stratum, because the close front shield that is pushed by the shield machine balances the earth and water pressure.
