APPLING IN THE OPTIMIZING OF PROTECTIVE SCHEME OF LOESS-SLOPE WITH FUZZY SYNTHESIZE ESTIMATE

The method of fuzzy synthesize estimate was applied to optimizing the Protective Scheme of Highway Loess-High-Slope basing on the study works for protective technology of highway loess-high-slope. The synthesize slope ratio、Texture-sequence model、the height of slope、slope shape、rainfall and constructive conditions were considered as the most important aspects which influence the election of Scheme, and mathematical expressions of estimating factors 、the first step fuzzy evaluation model 、the weight coefficients of these six judgment indexes and the optimizing matrix were ascertained. Finally, the engineering example is analyzed by this method and the results show that the method is reasonable.
