摘要
为确定苏州河两岸防汛墙改造的墙顶高程,采用水文概率统计与水力模型计算相结合、原型实测与数学模型相结合的方法,与太湖流域河网水文水动力模型相衔接,建立基于数字河网的苏州河水系水文水动力模型,从影响苏州河高水位的洪、涝、潮、控等要素着手,计算分析洪、涝、潮单一水情以及历史典型年不利水情影响下的苏州河高水位分布规律。研究结果表明,现状及规划近、远期工况条件下的苏州河沿线设计高水位分别为4.60 m,4.79 m和4.77 m。
In order to determine the crest elevation of flood-prevention wall rehabilitation along Suzhou River, by means of the combination of hydrological probability statistics and hydraulic test, mathematical model and prototype observation, a hydrological and hydrodynamic model for Suzhou River system based on digital river networks is established. It is integrated with the hydrological and hydrodynamic model for Taihu Lake basin. The factors for the high water level of Suzhou River are analyzed, including floods, waterlog, tides and control. The distribution of the high water levels of Suzhou River under the unitary condition of floods, waterlog and tides as well as the typical historical hydrological record is calculated and analyzed. The results show that the design high water levels under the current, short-term and long-term planning conditions are 4. 60 m, 4.79 m and 4.77 m, respectively.
