摘要
基于人工回填边坡、自然边坡和岩质边坡的粘聚力、内摩擦角、重度、孔隙水压力、坡角、坡高、岩土体类型、植物发育特征、降雨强度和过程降雨等10个指标的调查结果,采用突变理论与模糊数学相结合的方法对边坡稳定性进行分析。结果表明碎石土人工回填边坡和岩质边坡总突变隶属度分别为0.7467和0.7722,均处于较稳定状态;粘性土自然边坡总突变隶属度为0.6026,处于较不稳定状态。该评价体系适用于边坡稳定性评价,具有良好的实用价值,可为边坡防护提供参考和依据。
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 theory 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 catastrophe 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.
