Study on simulation and optimization of tunneling with TBM for long tunnel

The working procedures of the tunneling with TBM are various and the rate of the tunneling footage is greatly affected by the combination of the machineries and the coordination of the working procedures, so the tunneling process is necessary to be simulated. At present, the techniques of the Cyclic Operation Network (CYCLONE) and CPM are widely used in the simulation of the construction concerned; however, the simulation of the whole construction process with combining both the techniques together makes it possible to gain the reasonable combination of machineries to optimize the construction schedule during the tunneling with TBM; by which better coordination of all the working procedures during the tunneling can be realized, and then the TBM tunneling technique can be used successfully as well .
