Abstract
Combined with the practical situation of highway engineering construction period, the influencing factors causing larger post-construction settlement in soft foundation section are analyzed. Based on the principle of maximum correlation coefficient between evaluation value and optimal value of sample under different constraints, an evaluation model for the relative importance of influencing factors has been established using cluster analysis, rough set theory and expert system knowledge. The results showed that among many influencing factors of post-construction settlement, the thickness of soft soil layer has the most significant influence on post-construction settlement; then followed by pre-pressing time; the depth of fill has the relatively small influence.关键词
