Analysis on Backwater Calculation of Ice Jam during Ice-Flood Period

Abstract:

Article Preview

The river ice is a commonly natural phenomenon in the cold region. And serious ice situation can cause the ice-flood disaster. So the impact assessment on ice situation is an important factor which need considering in development and utilization of water resources. Based on the backwater calculation of ice jam in ice-flood period, and take the reach near Dazhunzeng Second-line Yellow River Railway Bridge for example, the backwater calculations of ice jam are carried on for the conditions before and after the construction of Dazhunzeng Second-line Yellow River Railway Bridge, and the conclsions are drawn that: (1) the construction of Dazhunzeng Second-line Yellow River Railway Bridge has less influence on the ice-flood control during freezing period; (2) after the construction of Dazhunzeng Second-line Yellow River Railway Bridge, during river-ice breakup the bridge section is combined affected by the old and new bridge, as a result the backwater height before the ice dam of bridge section is about 7.59m, and the ice surface elevation of the bridge section is up to 981.80m; (3) According to the current operation mode of Wanjiazhai Reservoir, the construction of Dazhunzeng Second-line Yellow River Railway Bridge will not have bad impact on the operation of Wanjiazhai Reservoir.
