巴音河（德令哈市区段）河道治理工程

设计总说明

巴音河发源于祁连山的古尔班安格尔，全长326km，由东向西经蓄积峡，泽令沟到黑石山水库，贯穿德令哈市区，下游再由东向西通过郭里木戈壁乡最终注入克鲁可湖，流域面积7782km。巴音河（德令哈市中心段）河道治理工程地处德令哈市中心，巴音河流域夏秋多暴雨，加之山区地面坡降陡，汇流时间短，来势凶猛，以致造成洪水灾害，冲毁农田、林木、房屋、桥梁、道路，管路及输电线路等，使国家及人民生命财产受到严重损失。

据统计资料显示，巴音河因暴雨洪水形成的灾害多次，造成450亩土地变成河滩，农田无法耕种城市土地无法利用，并有680亩耕地受到洪水威胁，大洪水还危及德令哈火车站及铁路２KM多，危害县级公路20km，还有两岸居民及工矿企事业单位数家时常受到洪水的危害，青新公路、德新公路、涩～宁～兰输气管道、兰西光缆及110kv输电线路等国家重要设施也受到洪水的威胁及危害，平均每年抗洪抢险耗费的人力、财力折合人民币高达500多万元，严重地制约着城市经济发展。

河岸坍塌严重，危及河道两岸的居民，厂矿及国家重要设施，耕地等安全，同时严重影响了德令哈市的市容市貌，单靠黑石山水库的调洪，还不能从根本上改观洪水对德令哈市及两岸的危害，河道两岸为第四系胶结砂砾石，结构比较松散，由于常年受洪水冲刷，河岸坍岸，河道变宽，侵占了道路和危机房屋，防洪压力较大洪水季节需投入大量的人力、物力、财力进行防洪抢险。由于河道的冲刷变形，除对德令哈市的城市规划造成一定的影响外，对下游青新公路、青藏铁路、输气管道、光缆以及输电线路等重要建筑物威胁极大，巴音河德令哈市中心段河道治理工程，正是鉴于以上情况修建两岸防洪堤，使洪水纳入河槽，避免乱冲刷，除保护区内建筑物和居民生命财产安全外，还可利用两岸修建绿化带和河槽中的溢流坝增加绿地和水面面积，美化周边环境，提高和改善居民的生活质量，拓宽生活空间。市区环境的改善和对洪水有效的保护，还可改善投资环境，促进区内经济和社会的发展和人民生活质量的提高，因此巴音河市区段的防洪治理是十分必要的，也势在必行。

巴音河河道总长326km，径流主要以融冰融雪水补给为主，降水补给为次，属混合补给型河流，多年平均流量10.2m3/s，年径流量为3.2×108m3。工程区段巴音河的区间来水为白水河，白水河在黑石山水库下100m处汇入巴音河，其多年平均流量为1.0m3/s，年径流量3154×104m3。

巴音河多年平均输沙量为26.6万吨，主要输沙量集中在7～8月份，仅这两个月的输沙量就达21.14万吨，占全年输沙量的79.47%，5、6、9三个月输沙量为4.75万吨，占全年输沙量的17.86%，其余七个月的输沙量仅占全年输沙量的2.67%。

根据河道的实际情况，根据工程区地质、地形条件，结合工程具体情况，并根据新疆库尔勒市孔雀河，西宁市北川河、西川河、湟水河等已建防洪堤的堤型来选择合适的堤形，并通过方案比较，

最终确定最优的堤形。为了在河道形成水面，结合两岸的园林城市景观设计，拟在市中心柴达木桥至格尔木桥之间设置两座挡水建筑物。另外，经德令哈市统一规划设人行廊桥1座。

BAYINHE (SECTION OF CENTER OF DELINGHA CITY) RIVER-MANAGING

PROJECT

THE TOTAL INSTRUCTION OF DESIGN

BaYinHe originated in the QiLian Mountains Gurban anggir. Total length is 326 km from east to west

by the accumulation Gap, zelinggou to Heishishan Reservoir, DeLingHa run through urban areas, further downstream from east to west through the Gobi Rural Silimuq Guo eventually be injected Krum Lake Basin area 7782. BaYinHe (DeLingHa City Center), located in the river project in the center of DeLingHa city, eastern River Basin over the summer rainstorm, Moreover, steep mountain slope, the ground,

convergence time is short, ferocious, resulting in floods, destroyed farmland, trees, houses, bridges, roads, pipelines and transmission lines so that the country and people's lives and property losses. According to the statistics, BaYinHe is formed by the rainstorm and flood disaster several times, resulting in 450 acres of land into a flood. not cultivated farmland can not use city land and 680 acres of farmland threatened by the flood, Flood threatens DeLingHa railway stations and two KM, endangering County Highway 20 km, There strait residents and mining enterprises in a number of often flood hazards, the Green new highways, new highway Germany, Ming acerbic ~ Portland gas pipeline, Lance R. Cable and 110 kv transmission lines and other important national facilities is also the threat of flooding and damage, The average annual cost of flood prevention of human, financial yuan worth up to 500 million severely restricts urban economic development. Riverbank collapses seriously endanger residents on both sides of the river, mines, factories and important national facilities, the land of safety, Meanwhile a serious impact on the city of DeLingHa face of the city, alone HeiShiShan Reservoir flood. not been able to fundamentally change the flood of DeLingHa City, and cross-strait hazards, the river between the two sides of the fourth cemented gravel. is a loose structure, as perennial flood erosion, riparian collapse shore, the river broadens, and the road and occupied housing crisis. flood the flood season pressure on the need to put in a lot of human, material and financial resources for the flood control and rescue. As the river erosion deformation, in

addition to the city of DeLingHa city planning have a certain influence, the lower reaches of the Green new highways. Qinghai-Tibet railway, gas pipelines, fiber optic cables and transmission lines and other

important buildings tremendous threat, BaYinHe DeLingHa city center of the river training works is the light of the above construction of the strait, breakwaters so that flood into the channel, to avoid chaos erosion, in addition to protecting residents of the district buildings and the safety of life and property, also utilizes the construction of green belts and the spillway channel to increase the surface area of green space and beautify the surrounding environment, enhance and improve the people's quality of life, expand the living space. Improve the urban environment and the effective flood protection, but also improve the investment environment, promote regional economic and social development and people's quality of life. Therefore BaYinHe of urban flood control is necessary, is imperative. BaYinHe chief River 326 km,

mainly in the runoff of melting ice water supply mainly snowmelt and precipitation to recharge times. is a mixed supply rivers, the average flow of 10.2 m3 / s, annual flow of 3.2 x 108m3. BaYinHe engineering segments of the water supplied to the turbine of BaiShuiHe interval, in a dark BaiShuiHe River on the Rock Hill Reservoir under 100 m into the eastern River, its multi-year average throughput of 1.0 m3 / s, annual flow of 3,154 x 104m3. BaYinHe average sediment load of 266,000 tonnes, mainly concentrated in the sediment ~ August 7, only two months sediment reached 211,400 tons, accounting for the annual sediment load 79.47%, 5,6, 9 sediment three months to 4.75 million tons, accounting for annual sediment load

17.86%. The remaining seven months of the year amount of sediment, sediment only of 2.67%. According to the actual situation in the river, according to engineering geological, topographical conditions, and in combination with specific circumstances, according to the XinJiang KorLa City KongQueHe, XiNing City BeiChuanHe, XiChuanHe, HuangShuiHe such as breakwaters built the dike to choose a suitable type of shape embankment, and through the program, ultimately to determine the optimal shape of the embankment. To form water in the rivers, with the two sides of the garden city landscape design, to the center of town Qaidam Bridge to Bridge between Golmud installed two water retaining structures. In addition, the unified planning DeLingHa city established the People's Bank of a lounge bridges.
