针对崖门航道所在海域水流、地形及泥沙特点,从悬移质不平衡输沙方程出发,导出估算挖槽回淤的计算公式,根据实测资料和潮流数值计算确定其中主要参数,并用1990年崖门试挖槽回淤资料确定公式中待定的综合系数。在此基础上估算了航道浚深不同方案的回淤强度与回淤量,并结合实际对结果进行了分析,结果表明航道回淤总体上并不严重,航道及所在海域基本上处于平衡微淤状态。

Based on the characteristics of flow, topography and sediment of the sea area where Yamen waterway is located, the formula for assessment of the waterway's sediment deposition is derived from the equation of non-equilibrium sediment transport of suspended material. The major parameters are determined from the numerical simulation of tidal and field data. And the general coefficient is determined from the sediment deposition data of Yamen waterway's dredging up which is as a trial in 1990. Based on all of these, various projects' deposition strength and quantity are calculated and the solutions are analyzed, combining the observed data. Solutions show that the deposition of Yamen waterway is not significant. The sea area where the waterway located is in a balance state and little deposition.
