Abstract
Slope protection construction of river levee is an important content of city flood controlling and river repairing. To find out the best slope protection scheme with optimal comprehensive benefits,the projection pursuit classification model was introduced,and the index system including basic function,construction difficulty,construction cost,project durability,landscape aesthetics,environmental harmony,et al was established. The model and the system were applied in a case,to select the best slope protection scheme. Results showed that this model avoided the limitation of using subjective weight singly,the calculations followed the regulatory of original data,and the principle was more scientific,which had great promotion and application value in the water conservancy project selection. As the calculation results of the model,the best slope protection scheme of outside Qinghuai river levee was the articulated chain bricks,following by the vegetation -type ecological concrete plus planting protection.关键词
