摘要
利用实测水位、流量资料,基于丹麦Mike11系统模型建立了双台子河感潮段水动力模型。模型率定和验证结果表明,监测点张明甲站的模拟水位与实测水位结果吻合较好,所建模型能够反映河网水动力条件。考虑上游不同频率洪水位、下游高潮及区间强降雨遭遇的多种不同水力组合,分析干流及支流的最高防洪水位。同时,以建闸以来最大洪水为例,模拟了现状河道在此不利条件下的洪水位。分析表明,双台子河和绕阳河的现状河道的防洪能力较低,不能抵御高位洪水。
Based on measured water level and flow data, a hydrodynamic model for tidal river network in Shuangtaizi River Basin is established by using Mikel 1. The calibrating and validating of the model shows that the simulated water level at Zhangmingjia Monitoring Station is good agreement with the measured value, and the model can reflect the hydrodynamic conditions of study area. The flood levels in study area under different hydrology combinations of upstream inflow, tide level and rainfall in study area are analyzed by the model, and the maximum flood level under the most adverse hydrology combination is also calculated. The results show that the existing flood control capacity of Shuangtaizi and Raoyang rivers is lower and can not meet the requirements.
