Multi-layer Fuzzy Synthetic Decision for Soft Ground Improvement Scheme

The development of the theoretical research on the filling roadbed treatment is rather backward and cannot satisfy the requirements for site construction.This paper proposes a more reasonable and relatively simplified filling roadbed treatment scheme based on the analysis of the various factors for the scheme optimization of soft ground improvement by taking advantages of the combination of fuzzy theory and analytic hierarchy process(AHP) in systematic engineering.According to the analysis of the various influencing factors of the optimized soft foundation treatment on the comprehensive construction along the eastern coastal areas in Xiamen,Fujian,the evaluation model and influencing factors are determined for the scheme.The weight of influence factor is determined by AHP,while the degree of membership of comment is determined by fuzzy theory.The testing of the judgement matrix is completed through the mathematical programming software(Matlab).The calculation results show that this method is more accurate and practical.
