The invention belongs to the technical field of equipment adaptive model selection, and provides a shield tunneling machine model selection system based on the geological prospecting situation. The shield tunneling machine model selection system based on the geological prospecting situation comprises a shield type decision analysis module, an earth pressure balance shield analysis module, a slurrybalance shield analysis module, a screw conveyor system analysis module, a shield diameter analysis module, a propelling system analysis module, a main driving system analysis module, an articulatedsystem analysis module, a turning radius analysis module, a cutter system analysis module, a bentonite system analysis module, a shield tail length analysis module and a slurry pump analysis module; all analysis modules can perform analysis comparison on all key technical parameters of the shield tunneling machine, according to analysis comparison, analysis reports of all shield tunneling machineson geological adaptability are obtained, and the shield tunneling machine selection results are judged according to the reports. Accordingly, model selection at any time for shield equipment is achieved, and the technical guarantee is provided for safer and more efficient construction.
