双台子河闸位于辽河下游感潮河段,枢纽工程中的新建浅孔闸为低水头高淹没度的拦潮闸。由于受到海潮的影响,在涨潮时,海水携带大量的泥沙并沉积在闸下,导致拦潮闸下游处于淤积的状态,下游河床由于淤沙的沉积而不断抬升。为有效解决河道抬升及淤沙问题,在水工模型试验的基础上,通过多种闸门调度运行方案并结合定床和动床调度试验,测量和分析了不同闸门开启方式下的流速、流态等水力要素及动床冲刷情况,得到科学合理的闸门调度方案,即隔孔开启,可有效改善双台子河闸闸下淤沙问题。
Shuangtaizihe sluice is located in the tidal reach of the lower reaches of the Liaohe River. The new shallow sluice gate in the hub project is a tidal barrage with low head and high submergence. Due to the impact of the tides, the sea water carries a large amount of sediment and deposits under the gates during the high tide, resulting in the siltation of the downstream of the tidal flats. The downstream riverbed is continuously lifted due to sediment deposition. In order to effectively solve the problem of river lifting and silting, based on the hydraulic model test, a variety of gate scheduling and operation plans combined with fixed bed and movable bed scheduling test were used to measure and analyze the flow rate and flow pattern under different gate opening modes And other hydraulic elements and the impact of moving bed scrubbing to get a scientific and rational gate scheduling program, that is, open the hole, which can effectively improve the silt sediment under the Shuangtaizihe sluice.
