Cloud model for shrinkage-swelling property classification of untreated and lime-treated expansive clays
摘要
Abstract
A shrinkage-swelling property evaluation model based on the cloud model is studied to consider the fuzziness and randomness of evaluation indicators as a whole and to achieve the qualita-tive and quantitative conversion.First,the cloud digital features of each indicator at different levels are generated based on the shrinkage-swelling property classification standard.And the generation al-gorithm of normal cloud is adopted to analyze the certainty degrees of measured indicators to each evaluation standard.Then the comprehensive certainty degrees are obtained according to the meas-ured data and the weights of evaluation indicators,and the swelling-shrinkage grade is determined by the maximum comprehensive certainty degree.Finally,a case of foundation treatment plans of dif-ferent lime contents in the runway area of Xinqiao International Airport in Hefei is used to confirm the reliability of the proposed model.Moreover,a comparison of results with the set pair analysis method,the variable fuzzy sets method and the fuzzy set method is also conducted.It indicates that the model used to classify the shrinkage-swelling grade of untreated and lime-treated expansive clays is feasible and effective,and can well describe the actual situation.关键词
