| 摘 要： | 河水位对堤内地下水有重要的影响,且河水向二岸的侧渗常导致堤内排水困难,使农作物遭受渍害。针对汉江中下游典型的二元土壤结构,利用V isualM od flow建立地下水流数学模型,模拟分析堤内地下水位和沿程“向上补给”流量随河水位变化的规律。为了排水降压,将渗流模型简化,导出排水沟深度和间距的计算公式,并用数值法验证了该处理方法的正确性。研究成果可为河岸渍害的防控提供理论依据。

| Abstract: | The groundwater is influenced severely by the river level and the river infiltration often causes in difficulties of drains and makes the crops along the riverside suffer from subwaterlogging.Aiming at the typical dual soil structure extracted from the Hanjiang River midstream and downstream,this paper develops a groundwater model with Visual Modflow,and simulates and analyzes the groundwater table and the "upward recharge" varying with the river level.For the decreasing of groundwater table,the infiltrating model is simplified and a formula is derived which is usable for determining the depth and interval of drainage ditches.The study results can be viewed as theoretical foundations for subwaterlogging prevention and control. |
