Study of Advance Surrounding Rock Classification Based on TSP203 and Extenics
In order to conduct tunnel advance surrounding rock classification effectively, puts forward an advance surrounding rock classification method based on TSP 203 system and Extenics. The method extracts the useful information from the detection results of TSP 203, establishes the indicators system of advance surrounding rock classification and adopts extensible comprehensive evaluation method to conduct advance surrounding rock classification. In the progress of establishing surrounding rock advance classification index system, adopts six rock classification parameters which TSP203 could identify effectively. They are rock mass integrity coefficient, Poisson's ratio, static Young's modulus, the angle between main structural surface and the tunnel axis, discontinuous structural surface and the state of groundwater. Finally, the method is applied to practical engineering and the results show that the method has higher prediction accuracy in advance surrounding rock classification and provide a new idea for advance surrounding rock classification.
