基于突变理论与模糊数学的边坡稳定性评价OA

Based on the investigation results of 10 indicators,including cohesion,internal friction angle,unit weight,pore water pressure,slope angle,slope height,rock-soil type,plant development characteristics,rainfall intensity,and process rainfall of artificial backfill slopes,natural slopes,and rock slopes,the slope stability is analyzed using a combination of catastrophe theo-ry and fuzzy mathematics.The results showed that the total catastrophe membership degree of the gravel-soil artificial backfill slope and the rock slope were 0.7467 and 0.7722,respectively,both of which were in a relatively stable state;the total catas-trophe membership degree of the clayey soil natural slope was 0.6026,which was in a relatively unstable state.This evaluation system was suitable for slope stability assessment,had good practical value,and could provide reference and basis for slope protection.
