　流域、河流及其水利、航运发展规划概况

　2.1.1.1

　流域、河流概况

　××流域位于××省中部，由××、××、××、××、××二市三县环抱，东西长 54.5公里，南北平均宽 15.1 公里，湖岸线最长 181 公里多公里。最大水域面积约 825 平方公里，最大容积 48.10 亿立方米，最大深度 0.98～7.98 米。湖水主要靠地面迳流补给，流域面积为12938 平方公里，集水范围包括××，××、××，××，××，××、××等两市五县。沿湖共有河流 35 条。其中较大的河流有××河、××河、×河、××河、××河、××河、×河等。从南、西、北三面汇入湖内，然后在××市城关出湖，经××河东南流至××口注入长江。

　下游河流：××河，西起××东口门，东南至××口入长江，是××唯一的通江河流。沿途有××河、西河等较大支流，流域面积 3808 平方公里。××流域水系图见图 2.1-1。

　××线航道是××经济圈通往长江的唯一水上通道，是××省“两干三支”国家高等级航道中的一支。该航道起点为××市××新港，终点为××河入江口，由××河、××、××河三段组成，全长约 138km。××线航道和利用水系图见图 2.1-2。

　航道现状

　××线航道主要由××河（××新港～××）、××（××～东口门）、××河（东口门～××口）三段航道组成，全长约 138km。在××口和××口建有 1000t 级船闸。

　××河航道：从××新港至××港综合码头，航道约 6km，有弯曲段航道 9 处，弯曲半径大于 320m，河槽宽 73～106m，能常年通航 500t 级船舶；从××港综合码头至××，航道里程约 17km，大部河段顺直微弯，仅在×河、××处河道呈明显弯曲状态，弯曲半径 440～500m，河槽宽 25～118m，大部分时间内能通航 1000t 级驳船。有沪蓉高速公路桥一座，满足Ⅲ级航道通航标准。

　××航道：从××至东口门，全长约 53km。经过 20××年对××、东口门等段疏浚后，××湖区航道基本稳定，水深可维持 2.0～2.5m。××湖区航标按一类航标配布。

　××河航道：从东口门至××口，全长约 62km。目前××河现河槽底宽已达 100m 左右，河道底高程 3.59～1.49m，比降为 5 万分之一，滩地宽 15～20m，河槽边坡 1：3，堤距约 200m，堤顶高程为 11.49～13.49m。××河××闸下～后河口段长约 23.6km 河道平面多弯，经人工裁弯后航道从取直后的河汊通行，弯曲半径满足Ⅲ级通航标准要求。后河口～黄雒河口4.1km，河道顺直微弯，黄雒河口～雍南镇 25.6km 河道顺直，雍南镇～××闸河道长约 4.9km，在雍

　××枢纽现状

　××枢纽主要包括节制闸及船闸，1959 年 10 月开工，1962 年 12 月竣工，由节制闸、船闸、引河及导流堤等组成，具有防洪、排洪、蓄水、引水灌溉及通航多种功能。××闸引河上连××，下接原××河，基本呈直线布置，河轴线自北向南偏西约 30°，20××年加固扩建后，河底宽 100m。节制闸布置在引河的左侧，老节制闸共 10 孔，每孔净宽 5m，底坎高程4.0m，为满足排洪要求，于 20××年进行了扩建，扩建闸闸室为潜孔式，单孔净宽 5.0m，共6 孔，高 7.5m，底坎高程 4.0m，节制闸总设计流量 1370m³/s。

　××一线船闸位于引河的右侧，与节制闸平行布置，两闸中心距约 128m。老船闸设计采用原苏联三级标准，闸室长 195.0m，净宽 15.00m，底坎高程 3.5m。上下闸首均为钢筋混凝土结构。闸门均采用横拉门，齿条式启闭机。

　××复线船闸 20××年 10 月底完工，船闸等级为Ⅲ级，设计最大船舶吨级为 1000t，船闸尺度为 230×23×4.5（m）。船闸位于老船闸右岸，与现有一线船闸基本平行布置，新、老船闸中心相距约 80m。上下游导航墙长 60m，上游靠船墩长 330m，下游靠船墩长 325m，上下游各布置靠船墩 16 个。设计最高通航水为上游侧 12.49m，下游侧 11.88m，设计最低通航水位，上游侧 7.7m，下游侧 6.42m。

　××船闸水运量现状、船舶营运现状

　目前，××船闸过闸货运量主要为××流域与长江流域的物资交换。根据××船闸过闸船舶统计资料，20××年××船闸船舶通过量为 4748 万吨，货物通过量达到 2863 万吨，船舶装载率超过 60%。其中上行货物通过量 2212 万吨，占比 77.3%；下行货物通过量 651 万吨，占比 22.7%。过闸货物主要为从长江上行往××方向调入。

　从××船闸历年过闸货运量的增长趋势来看，20××年该船闸过闸货运量为 800 万吨，到 20××年增长至 2863 万吨，年均增长 29.0%，运量增长明显。
