Determination of Big Span Longitudinal Scour Depth Confirmation of Yellow River's Wandering Riverbed

Tower foundation's longitudinal scour depth is important technical index to analyze tower foundation's least buried depth and appraise foundation's safety and economy.Based on Yellow River's historical data and corresponding tower foundation's calculated longitudinal scour depth,this paper analyze the reliability of calculated result by formula.The paper introduces main problem need to draw attention during local movable bed model test.By contrast test result and calculated result by formula,this paper finally confirm the longitudinal scour depth,which can provide reasonable design gist of tower foundation's least buried depth.
