针对河道开挖后挖河效果预测的重要性 ,初步提出了预测挖河效果的三个评判标准 :挖沙减淤比、复原率和稳定坡。引用黄河山东河段“挖河固堤工程”资料 ,通过数学模型计算结果对挖河效果预测的三个评判标准进行了说明 ,并展示使用三个评判因子分析挖河效果的有效性和应用潜力。
Aiming at the importance of dredging effect after river excavation, three criteria for predicting the dredging effect are preliminarily proposed: dredging dredging ratio, recovery rate and stable slope. By referring to the data of digging river embankment works in Shandong reach of the Yellow River, the three criteria for predicting the effect of digging river are illustrated by the results of mathematical model calculation, and the effectiveness and potential of using the three factors to analyze the effect of digging river are demonstrated .
