| 中文摘要: |
| 本文在深入分析三门峡水库运用方式与潼关高程的关系以及潼关高程不同阶段升高原因的基础上, 采用非均匀不平衡泥沙数学模型, 探讨了三门峡水库运行方式、来水来沙条件、跨流域调水、河道整治、裁弯、疏浚、水库增大泄流规模等措施对降低潼关高程的作用。指出为使潼关高程进一步有比较明显的降低, 应采取多项措施的组合。 |
| 英文摘要: |
| On the basis of a comprehensive analysis on the relationship between water level variation at Tongguan station in the lower reaches of the Weihe River and operation modes of Sanmenxia Reservoir and on the basis of an analysis on the reasons of rising of Tongguan water level in different periods, a sedimentation mathematical model of non-uniform and non-stable flow was established to study the effects of lowering the water level at the Tongguan station by the act ion of the following items. These items included: operation modes of Sanmenxia Reservoir, sediment transport, the condition of water and silt inflow, inter basin water diversion, river channel regulation, river channd cutoff, channel dredging, increase of reservoir discharge capacity. Results suggest that comprehensive measures should be taken to further lower Tongguan water level. |
