摘　　要：在河网地区,为控制河道水体循环、改善河流水环境质量,需要越来越多的利用水闸联合调控技术。但利用数学模型精确模拟水闸控制对水动力过程影响的技术尚不成熟。利用面向对象思想和三级联解法并结合MPI和OpenMP并行编程技术,开发了潮汐河网水动力模型TRNM(Tidal River Network Model)。将该模型用于珠江三角洲市桥河网,利用实测水文资料对模型进行率定后,模拟了市桥河上雁洲水闸建闸前后不同调度方案对市桥河水动力过程的影响。模拟结果与实测结果吻合良好,并行算法大大提高了模型的计算速度。In river network area, co - control technology by sluices is more and more applied in the flow control of river channel to improve water environmental quality, but the simulation technology to hydrodynamic process influenced by sluice control is not yet accurate enough. A tidal river network hydrodynamics model （TRNM） was developed using object oriented programming and 3 grade co - solution technology, while combining MPI and OpenMP parallel programming methods. The model was applied to Shiqiao River network and calibrated with survey data, and the calibrated result showed good consistence with the survey re- cord. Using the developed model, impacts of different sluice operation plan on hydrodynamic process of the Shiqiao river network before and after Yanzhou sluice building were simulated. The simulation results are satisfactory and the parallel programming technology improves the computation efficiency significantly.
