摘　　要：为研究双堤掩护下水沙运动规律,简化内航道淤积计算,以水流连续方程和泥沙运动方程为基础,通过解析求解,得出了双堤掩护下水域的泥沙运动特点,导出了掩护式内航道的淤积计算的公式,考虑因素全面,方法简单实用,可供科研和设计应用。In order to study the movement law of flow and sediment in the waterway shielded by double breakwater and to simplify the siltation calculation of inner waterway,the analytical solution was obtained according to the continuity equation of flow and sediment movement equation. The characteristics of sediment movement in the area shielded by double breakwater were summarized,and the formula calculating the siltation of the shield type inner waterway was further deduced. Considering all factors,the method is simple and practical,and it can be referenced for scientific research and design.
