| 摘 要： | 天然岸坡同港口码头排水岸坡的渗流场相比较,地下水运动规律各不相同,用传统的方法求解码头岸坡渗流自由面是很困难的,为此提出了基于竖直平面二维流的渗流自由面计算常微分方程,运用该方程可通过解析计算精确得到港口岸坡渗流自由面的分布和随时间的变化规律,消除了复杂的计算过程,计算方法简单,计算结果可靠,能有效地指导库区港口码头建设和地质灾害防治.

| Abstract: | Comparing the seepage field in natural shore with port shore,the law of groundwater seepage is not the same.Solving the port shore seepage free surface by traditional method is very difficult.So the authors brought forward a calculation method for seepage free surface based by constant differential equation in planar seepage field.By Using the equation,the authors obtained the distribution of port shore seepage free surface and its change to time by analytical calculation.The method is very simple and avoid complicated calculation process.The result is credible and can effectively guide the port construction and geologic disaster preventions in Three Gorges reservoir. |
