In the waterway reconstruction engineering,it is often necessary to compare and select multiple schemes for the revetment structure because of the complex environment on both sides of the waterway.However,most of the comparison and selection are based on the subjective judgment of qualitative analysis,which often has some limitations.Taking the optimization of the revetment structure of the first section of a comprehensive regulation project of a waterway in Shanghai as an example,aiming at the typical section of revetment,this paper uses the grey relation analytic hierarchy process to seek a safe,reliable and economic reasonable revetment structure scheme.In view of the special section of revetment,the paper analyzes the special environmental conditions commonly encountered,and finds out the technically feasible and ideal revetment structure scheme.The results of this paper can be used in similar projects.
