摘要
Abstract
Taking the highway diversion project in Fubao section from Xingxian to Baode over the north stream of the Yellow River as back-ground,based on the site survey as well as the analysis of scour and silting evolution and the flood characteristics,the study determined the design flood. Based on the project,the clean-water movable-bed model was used to test the scour depth of river bed at the embankment toe in the case of once-in-fifty-year frequency flood under different project boundary conditions. The results show that the average scour depth of the roadbed is 4. 21m,the maximum scour depth is 9. 04 m,and the deepest position is at the stake K0+500 under the conditions of the em-bankment under the bridge completely washed away;the average scour depth of highway roadbed is 4. 12 m,the maximum scour depth is 7. 56 m,and the deepest position is at the stake K0+800 under the conditions of the embankment under the bridge not washed away.关键词
