多沙河流泥沙冲淤埋深确定方法与应用

Method to determine the vertical depth induced by sediment scouring and deposition at the sediment-laden rivers and application thereof

确定多沙河流泥沙冲淤埋深是涉河工程基础性计算问题。在综合比较现有计算方法基础上,本文通过研究提出了基于泥沙多年冲淤平衡和历史最大洪水冲刷的埋深确定方法,并选取山东省典型河流进行了实例计算分析。研究结果对相关工程数值计算具有重要参考价值。

The determination of the vertical depth induced by sediment scouring and deposition of river bed at the sedimentladen river is one of the fundamental works for engineering relating to the sedimentation of rivers.The method to determine the vertical depth is put forward through study based on comprehensive comparison of existing computation methods.The method is based on scouring balance in many years and historic maximum flood scouring.The typical rivers in Shandong Province are chosen as case for computing analysis.The study results have important reference value for numerical calculation of related engineering.
