针对强采机理展开研究.首先制作一个砂槽实验模型模拟傍河强采地下水的物理过程,然后应用饱和-非饱和流理论建立其数学模型,通过计算机进行理论模拟.物理实验和理论模拟结果一致,并得到了一些新的认识和发现:剖面上的浸润曲线不是上凸的抛物线形状而是一条下凹曲线,随着傍河抽(排)水强度增大,地下水与河水产生脱节,脱节点不位于河床面而在河床下含水层内部;河床下形成上下两个饱和区.
Aiming at the mechanism of strong mining, a sand tank experimental model was built to simulate the physical process of groundwater pumped by the river and the mathematical model of saturated-unsaturated flow was established, and the theoretical simulation was carried out by computer.The results of physical experiment and theoretical simulation were consistent , And got some new cognitions and discoveries: the infiltration curve on the profile is not a convex parabolic shape but a concave curve. As the pumping (rowing) water intensity increases, the groundwater is disconnected from the river water, Not located in the riverbed and in the aquifer within the riverbed; under the river bed to form two upper and lower saturated areas.
