Earth Pressure Balance(EPB)TBM
When an EPB TBM bores, its cutter head in front rotates to excavate the soil into the muck chamber. When the chamber is full of mucks, its passive earth pressure is basically the same as the earth and water pressure exerted on the cutting face; resultantly, the balance of the face is realized and maintained (i.e. the faceis dynamically stable).
