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.

Triangular meshes method for land leveling earthwork calculation;

Articles published about land consolidation mostly discussed earth volume computation without mentioning land leveling project model,which is not favorable for the proceeding of land leveling.

Land leveling is one of the most important items in land consolidation,and the precision of land leveling not only affects the land quality after consolidation,but also has an impact on the investment and benefit.

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.
