【摘要】：为确保北京城市副中心的防洪安全,开展北京城市副中心防洪对策研究是十分必要的。因此,采用DHI洪水模拟系统中的MIKE11水动力模块,结合现有调度方式、工程条件和已有规划治理方案进行了防洪对策研究。经方案论证,按照分洪蓄洪相结合的方式进行防洪布局调整后,当河系发生100年一遇洪水时,与现状防洪布局情况下相比,潮白河北京境内河道水位增加约0.20 m,潮白河吴村闸处河道水位增加0.10 m,略微加大了下游河道的防洪压力;北运河京冀交界处洪峰流量有所减小。蓄滞洪区方面,100年一遇洪水条件下,大黄堡洼和黄庄洼分洪水量比现状布局分别增加200万m~3和300万m~3,基本不会影响蓄滞洪区安全运用。因此,通过开挖温潮减河和建设宋庄蓄滞洪区,形成分蓄结合的防洪布局是可行的。
[Abstract]:In order to ensure the flood control safety of Beijing sub-center, it is necessary to carry out the research on flood control countermeasures of Beijing sub-center. Therefore, using the MIKE11 hydrodynamic module in the DHI flood simulation system, combined with the existing dispatching mode, the engineering conditions and the existing planning and control schemes, the flood control countermeasures are studied. According to the scheme demonstration, after adjusting the flood control layout according to the combination of flood diversion and flood storage, when the river system meets the flood once in 100 years, compared with the present situation of flood control layout, The water level of the Chaobai River in Beijing increased about 0.20 m, and the water level at Wucun Gate of Chaobai River increased by 0.10 m, which increased the flood control pressure of the downstream river slightly, and the discharge of Hong Feng at the junction of Beijing and Hebei of the North Canal decreased. In the case of flood storage and detention area, the flood diversion capacity in Dahuangbao and Huangzhuang Wagas increases by 2 million mm3 and 3 million mm3, respectively, under the condition of once in 100 years, which will not affect the safe operation of flood storage and detention area. Therefore, it is feasible to construct the flood storage and detention area of Songzhuang by excavating the warm tide reducing river and constructing the flood storage area of Songzhuang.
