Abstract
In this paper, advantages and disadvantages of single evaluation methods in solution selection of soft soil foundation treatment are analyzed and evaluated. Grey multilevel evaluation model combined AHP method and GRAP method is used in method selection of soft soil foundation treatment. Three kinds of soft soil foundation treatment schemes to be adopted in breakwater engineering construction in the west area of Yantai port are analyzed. And optimal selection of soft foundation treatment schemes is realized. It indicates that grey multilevel evaluation methods is reliable in results and possesses certain practical applicability and effectiveness, which provides a new way for optimal selection for soft soil foundation treatment methods of port engineering.
