Tbm adaptive surrounding rock classification method
A TBM adaptive surrounding rock classification method includes following steps: establishing a TBM adaptability surrounding rock classification table; substituting the rock uniaxial compressive strength and a rock mass intactness index into the surrounding rock classification table to obtain basic classification of a surrounding rock; determining whether the grade of the surrounding rock needs to be corrected or not, and when correction is not needed, enabling the basic classification of the surrounding rock to be the final grade of the surrounding rock; when the correction is needed, performing rock burst correction or groundwater correction on the grade of the surrounding rock; determining which corrected classification of a rock burst correction result and a groundwater correction result is poorer in surrounding rock evaluation; and obtaining a conclusion, and taking the corrected classification with poorer surrounding rock evaluation as the final grade of the surrounding rock.
