The invention provides a tunnel safety construction control system, belongs to the field of tunnel construction, and aims to make dangerous situations pre-judged so that rescue and escape processes have linkage and coordination after the dangerous situations occur. The system comprises a positioning monitoring module collecting personnel information, a video monitoring module, a measuring module,an intelligent BIM control platform and an escape guiding module; the intelligent BIM control platform judges that surrounding rock is in a stable state according to dynamic deformation data of tunnelsurrounding rock and supporting structure, and judges that a work area is in a dangerous state according to video information; the danger category is identified according to the above, and a corresponding escape plan is made. The tunnel safety construction control system has the advantages that real-time information of tunnel structures, operating personnel and operation situation in the work area of a tunnel is integrated through the intelligent BIM control platform, the construction safety situation and operation personnel distribution in the tunnel can be known, so that the dangerous situations are prejudged, and the rescue and escape processes have the linkage and coordination after the dangerous situations occur.
