Seawater intrusion mechanism and its 3D numerical simulation are further explored and researched in this paper. On the basis of the classical theory of fluid mechanics, it built the ideal model of seawater intrusion, and attained the speed in flow field which gradually decreased along with the increasing distance of curvature center along the principal normal in the course of seawater intrusion.

以流体力学经典理论为基础，建立了海水入侵内陆的理想模型，得到在海水入侵内陆的过程中沿弯曲流线的主法线方向，流场中速度随着距曲率中心距离的增大而逐渐减小，根据流线上的速度分布，并可表示出流场中的流线方程，可确定一定条件下海水入侵内陆的速度和方向。

For zero offset and constant velocity, a buried focus occurs if the center of curvature lies beneath the recording plane.

对于零偏移和常速度情况，如果曲率中心位于记录面之下，则会形成地下焦点。
