By Visual Basic 6.0, monitor computer software of the system is completed, the program of system's self-diagnoses of controlling is worked out and the operation of traffic inducement and controlling under the three operations state of freeway tunnel is realized.
Through single opening development of 2.6km freeway tunnel,after outcrop of gas was discovered during construction in which trackless transportation was adopted,the scheme comparison and selection process for construction ventilation modes were proceeded,and it explained that when trackless trensportation scheme was adopted in the construction of small spacing,large cross section,long and big double(multiple)line tunnel,the double(multiple)cave and greater circulation ventilation mode has remarkable advantages.
