| 摘 要： | 由于沪汉蓉铁路交通要道需要进行提速,铁路部门拟在湖北汉丹线跨沦河处新建辛安渡大桥.沦河上修建桥梁必然会对河道水位和流态产生影响,为了分析辛安渡大桥对沦河的防洪影响情况,建立了非正交曲线坐标下平面二维水流数学模型,并应用该模型对沦河修建辛安渡大桥前后的水流情况进行了模拟.模型计算结果表明,桥梁修建后对工程附近河段水位和流速影响均较小,基本上不会对沦河防洪产生不利影响.

| Abstract: | In order to raise the train speed at Hu-Han-Rong Railway line,the department of railway plans to build the Xin'andu bridge at the Lunhe River on Han-Dan Railway line.Building a bridge at Lunhe River will influence the natural water level and velocity near the project.For analyzing the influence of Xin'andu bridge on flood control,the paper builds a 2-D non-orthogonal curvilinear coordinate flow mathematical model which applied to the Lunhe River.The computational results show that there is no obvious influence on water level and velocity in the Lunhe River after the construction;so the project will not bring disadvantageous influence on flood control basically. |
