摘要
根据冲积性河流自动调整原理 ,初步分析了 196 0年以来潼关上下游河段河道纵比降变化过程 ,剖析了1974年以后 ,特别是 1986年以来 ,潼关上下游河段纵比降调整与来水来沙的响应关系。进而说明近年来潼关高程不断抬升是潼关上下游河道纵剖面自动调整的必然结果。
Based on automatic adjustment elements of alluvial rivers, the changing process of slope in the upper and lower reach of Tongguan is analyzed since 1960. The responsive relationship between the slope in the upper and lower of Tongguan and coming water and sediment is also analyzed since 1974, especially after 1986. The results show that the continuous rising of water level at Tongguan in present years is the inevitable response of automatic adjustment of slope in the upper and lower reach of Tongguan.
