摘要:
为阐明峡江枢纽围堰施工期河道水力特征,指导工程施工,采用峡江站水文资料及枢纽实测水位,在率定好1维数学模型的基础上,建立了赣江峡江段平面2维水流数学模型,定量计算枢纽重要水域水流流态,分析流场形态的变化特征和局部流态对枢纽尤其是围堰的影响,并将研究结果与物理模型试验结果做了对比分析.结果表明2维数学模型能较准确地计算围堰工程局部水位及流场变化情况,峡江枢纽围堰施工方案可行.
Abstract:
In order to guide the cofferdam construction,the channel hydraulic characteristics were studied during the construction period.After verification the one-dimensional mathematical model with hydrological data of Xiajiang hydrological station and the measured water level at water control project dam site,a two-dimensional numerical model was developed to simulate waters region around the water control project with erodible bed and banks composed of well sorted-sandy materials.The waters flow pattern around the hub was quantitative calculated,the changes characteristics of flow and effects of local flow patterns for hub especially cofferdam were analysis,and the research results were compared to physical model rest results.The results show that the two-dimensional mathematical model can accurately estimate the local water level and flow field of cofferdam engineering changes,Xiajiang water control project cofferdam construction scheme is feasible.
