Abstract：
In light of the current reality of road tunnel construction, the sub-classification index system, which takes rock hardness and integrity as a basic index and groundwater status and occurrence of main weak structural surface as a correction factor during tunnel construction, is established by summarizing the indexes of a variety of surrounding rock classification methods at home and abroad. A sub-classification model was also set up based on quantification theory. The sample test demonstrated that this model is highly accurate and rational. Combined with programming techniques and database technology, a computer-aided sub-classification system of surrounding rock was finally developed, which basically realized automatic and intelligent management of the sub-classification.
