Abstract The matter element model of cavern rock quality evaluation is established using matter element model
theory based on extension engineering method. The stratification analysis method used to calculate weight
aggregation of evaluating factors is proposed. Through calculating the relational degree of the actual cavern rock
quality gradesthe rock quality of Shuibuya Waterpower Station cavern is evaluated by extenics and the
conclusion has good relation with the facts. It is shown that stratification analysis method is feasible to calculate
the weight aggregation of evaluating factors. The extenics evaluation of cavern rock quality with high applicability
can more precisely reflect the quality classification of the cavern rock.
