摘要
为了减少峡江水利枢纽工程修建后的淹没损失,保护同江河两岸1 920 hm2良田和4.26万人口,既使保护区内不被洪水淹没,也不致因库水位升高后引起保护区内地下水位的升高而影响农作物的产量。根据防护区勘测资料和区内水系情况,建立三维渗流模型,分析水库蓄水后防护区内的地下水位,绘制地下水位等高线,按照农作物生长期对地下水位的要求,分析判断浸没的范围。这种方法可对地下水位进行定量分析,与其它方法比较有一定的优越性,可供设计、研究参考。
n order to reduce the inundation loss caused by construction of Xiajiang hydropower project and protect 1920 hm2 farmland and 42.6 thousand people,we have to avoid the protection area inundated by flood and agricultural output reduction by underground water level rising in the area due to water level rising of reservoir.Based on the survey data and water system condition in the protection area,a 3-D seepage model is established to analyze the underground water level in the area after impoundment of Xiajiang Reservoir.We draw underground water-level isoline and identify the inundation scope according to the demand of growing season of crops.Thus,the underground water level can be analyzed quantitatively and this approach has some superiority compared with others.
