Study on the law of geology adaptability cutter selection for shield
Abstract：According to the complexity and fuzziness of geology adaptability cutter selection for shield,a new method of geology adaptability cutter selection based on fuzzy theory was proposed.Two factors affecting geology adaptability cutter selection-rockmass uniaxial compressive strength and integrity,were determined.Respectively,fuzzy adaptability relationship and adaptability membership functions of cutter versus the two factors were established through fuzzy mathematics theory.And a fuzzy synthetic evaluation model was established.Cutter selection for some kind of rockmass（Rc=75 MPa,RQD=66%） was carried out with this method.The results indicate that it＇s able to cut this kind of rockmass using single disc cutter.
