摘 要 夏仕港闸位于，其主要作用是、、AbstractXiashigang sluice is located in Jingjiang city, 1km to theChangjiang rever.It is built to protect Jingjiang Jiangyan and Taixing. Its main function is to release flood waters, tide, silt, and aided navigation.Sluice chamber section, connected by upstream and downstream connections in three parts.The chamber section includes a bottom plate, gate pier, pier, quay wall, gate, bridge work; upstream connection section includes upper wing wall, stilling basin, upstream erosion trough and upstream slope protection and other components; and downstream connections include the lower wing wall, stilling basin, downstream anti-scouring groove and the downstream slope protection five part.The design mainly includes the hydraulic design of sluice, energy dissipation and design, the seepage of sluice foundation calculation of lock chamber structure, layout, building layout, sides of the connecting chamber stability calculation, structure calculation of connected buildings on both sides of the chamber, structural calculation.Keywords: hydraulic calculation, calculation of seepage, stability calculation, structure calculation, elastic foundation beam method. 目录 1 工程概况 1 1.1 基本资料 1 1.1.1 建筑物级别 1 1.1.2 孔口设计水位 1 1.1.3 消能防冲设计 1 1.1.4 闸室稳定计算 1 1.1.5 地质资料 2 1.1.6 回填土资料 2 1.1.8 其他 2 1.2 工程概况 2 2 孔口宽度设计 4 2.1 闸孔形式的确定 4 2.2 孔口设计水位组合 4 2.3 堰型及堰顶高程的确定 4 2.3.1 堰型的确定 4 2.3.2 堰顶高程的确定 4 2.4 闸孔宽度的确定 4 2.4.1 拟定闸孔宽度 4 3 消能防冲设计 6 3.1 消能防冲水位组合 6 3.2 正向消力池设计 6 3.2.1 消力池长度的计算 6 3.2.2消力池底板厚度的计算 7 3.2.3 消力池构造的确定 7 3.3反向消力池设计 8 3.3.1 消力池长度的计算 8 3.3.2 消力池底板厚度的计算 9 3.3.3消力池构造的确定 10 3.4正向海漫设计 11 3.4.1海漫长度的计算 11 3.4.2海漫构造的确定 11 3.5反向海漫设计 12 3.5.1海漫长度的计算 12 3.5.2海漫构造的确定 12 3.6 正反向冲刷坑深度的计算，防冲槽尺寸的确定 13 3.6.1 冲刷坑深度的计算 13 3.6.2 防冲槽尺寸的确定 13 4 闸基渗流计算 14 4.1 渗流计算水位组合 14 4.2 地下轮廓线布置 14 4.2.1 地下轮廓线布置 14 4.2.2 验算防渗长度 15 4.3 闸基渗流计算 16 4.3.1 计算地基有效深度 16 4.3.2 计算各典型段的阻尼系数 16 4.3.3 各典型段渗压水头损失计算 17 5 闸室结构布置 21 5.1 闸室底板 21 5.2 闸墩 21 5.2.1 闸墩顺水流方向长度、闸墩高度 21 5.2.2 闸墩厚度、门槽位置和尺寸的拟定 23 5.3 闸门 24
