摘要
文中结合二维浅水动力学模型对辽宁省典型河流橡胶坝段的流态进行模拟分析。分析结果表明:由于橡胶坝的雍水作用,其上河道内水流流速及流向稳定,其下水流流速加快、流向变化增大,在下游礁石处产生扰流作用。研究成果可为为进一步分析水文站断面附近橡胶坝对水文监测的影响提供数据支撑。
The two-dimensional shallow hydrodynamic model is used to simulate and analyze the flow state of typical river rubber dam section in Liaoning Province.The analysis results show that,due to the damming action of the rubber dam,the flow velocity and flow direction of the upper channel are stable,the flow velocity and the flow direction changes in the lower stream are increase,and the disturbed flow action occurs at the downstream reef.The research results could provide data support for further analysis influence of rubber dams near the hydrological station section on hydrological monitoring.
