洪湖地区浅层承压水动态模拟研究

Study on simulation of confined water regime in Honghu district

洪湖地区长江深泓线标高一般在黄海基面5m以下,而承压含水层隔水顶板标高一般在9m以上,所以长江无疑已经切穿了承压含水层顶板,与其有着直接的水力联系.通过对洪湖地区水文地质条件调查,长江水位变化对浅层承压水动态影响强度、影响范围的分析,建立了一个模拟浅层承压水运动规律的动力学模型,该模型能较好地模拟出长江近岸地区浅层承压水动态规律.

Changjiang River has undoubtedly cut across the coping of confined water layer in Honghu district, and has direct waterpower relation with it because the standard elevation of Changjiang River's bottom in Honghu district is less than 5 meter above the Yellow Sea base level but that of the coping of confined water layer is up to 9 meter. Based on investigation of the hydrogeologic condition here and analysis of the intensity and the range that the water level change of Changjiang River influences the dynamic development of confined water, this paper set up a mathematic model to simulate the dynamic development of confined water in Honghu district. This model can reveal the dynamic development law of confined water near the shore of Changjiang River to some extents.
