汾河下游拦河闸是汾河综合治理改造工程的一部分,兼顾泄洪和美化环境两部分,一部分以泄洪为主,一部分以蓄水为主.蓄水河道内的蓄水主要籍洪水的尾水补充更换,并肩利用开发区专设的污水站补充征发与渗漏.正常泄洪河道在非汛期亦可蓄水运用.本河道治理改造工程实施后,将使太原市汾河河道的防洪标准达到三百年一遇,由于河道治理改造工程采用了全段面的固化防渗措施,河道蓄水不会对两岸产生浸没影响.由于河床粗糙率减小,水流流速较大,使洪水所挟泥沙能全部顺利过境.
治理改造工程实施后可有2576亩的建筑开发用地,加之河道蓄水形成110万平方米的水面,沿汾河两岸可以设计成公园,美化了太原市的环境,而且这里会成为一个新的经济,文化中心.
泄洪河道总宽96m,设6孔闸门,每孔净宽14m；蓄水河道总宽160m,设10孔闸门,每孔净宽14m,双向受力闸墩1.5m,缝墩1m,边墩1m,高6.5m,闸室宽度17m.本次设计的洪水标准为：以百年一遇洪水（3450 ）为设计标准,以千年一遇洪水（4450 ）为校核标准.水闸溢流堰堰型选用无坎宽顶堰,闸门采用4×14弧形闸门,上游做12m水平粘土铺盖,减小闸室底板的渗透压力,下游做14m的海漫,蓄水河道中部设有3米高橡胶坝一座.
水力计算中流量系数,侧收缩系数等按水工手册中规定的公式选取,淹没系数则按南京水科院提出的公式计算.消能工程设计考虑本地区水位变化较大不适和全面消能故采用底流消能方式,防止过堰水流对下游的冲刷,闸室抗滑稳定分析以平面滑动情况进行验算,在基本荷载组合和特殊荷载组合的情况下分别进行验算,闸室结构设计采用倒置悬臂梁法进行计算,考虑两种最不利受力情况作为水闸设计的控制条件.闸墩简化为矩形后再进行配筋计算,所用参数由《水工钢筋混凝土结构学》与《材料力学》查得.

Fen River Sluice is a part of comprehensive renovation project, taking into account flood discharge and landscaping of two parts, in order to discharge the main part with water-based. Water storage within the main river flood tail water added membership change, together use zone of the sewage station dedicated additional levy made and leakage. Normal river flood water can be used in non-flood season. The reform project of the river after the implementation will Fenhe river flood protection standard to three hundred years, due to river training works by transforming the entire surface of the curing section of seepage control, river water immersion does not produce effects on the two sides . As the rate of river bed roughness decreases, a larger flow velocity, so that flood sediment can all embrace the smooth transit.
The reform project implementation will have 2576 acres of land for building development, coupled with the formation of 1.1 million square meters river water surface, both sides can be designed along the Fen River Park, the landscaping of the Taiyuan city environment, but there will be a new economic and cultural center.
The total width of river flood 96m, set up six holes gates, each hole clear width 14m; the total width of river water 160m, with 10 holes gates, each hole clear width 14m, two-way force pier 1.5m, sewing pier 1m, side pier 1m, 6.5m high , chamber width of 17m. The design flood standard: to flood once every hundred years (3450) design standards to flood once in every thousand (4450) for the calibration standard. Sluice weir overflow weir type selected non-Hom weirs, gates by 4 × 14 radial gates, 12m to do the level of the upstream clay blanket, reducing the chamber floor of the osmotic pressure, downstream of the apron to do 14m, located in central water channel A 3-meter-high rubber dam.
Hydraulic calculation of flow coefficient, contraction coefficient of lateral hydraulic manual provided by the formula selected, according to the Nanjing water submerged coefficient formula proposed by ASTRI. Consumers can design water level changes in the region to consider a larger and full of energy dissipation it is not used for energy dissipation and the prevention of excessive erosion downstream weir flow, chamber sliding stability analysis for plane sliding checking the situation, the basic load combination and special load combination cases separately checking, chamber structure design method calculated using the inverted beam, consider two most harmful conditions designed to control conditions as a sluice. Pier reinforced later by a simplified calculation for the rectangle, the parameters used by the "hydraulic study of reinforced concrete structures" and "mechanical" look up.
