Using a microcomputer in the wind tunnel instead of conventional SCR drive controlling equipment has been studed in this paper.
The maximum displacement which takes on zonal distribution locates in tunnel vault and the minimum displacement locates in tunnel intrados. With tunnel excavated, these displacements increase slightly and drive to invariant gradually.
The application of variable-frequency variable-voltage technique in tunnel ventilation control can achieve blower's soft-start and stepless drive, this can extend the using life-span of blower, minimize noise and conserve the consumption of power.
Based upon the analysis of the working conditions in the tunnel excavations, a principle design, hydraulic value design and system integration design of hydraulic drive system of cutter head for simulator test rig is carried out theoretically with electro-hydraulic proportional control technique.
When the displacement over run the security line, it will pose a threat to the structural safety of the tunnel and the waterproof of the connectors, then it will influence the formation of the track, and drive the train accident.
