摘　　要：海啸在浅水大陆架的传播问题由于其非线性作用和浅水效应而变得十分复杂,然而目前成熟的海啸传播理论及数值模拟结果在这方面与实际并不一致。本文比较分析了可用来模拟大陆架海啸传播的浅水波模型和数值方法,并提出对我国东海陆架边缘可能发生的近海海啸需要开展数值试验研究。Tsunami propagation in the continental shelf becomes complex due to nonlinear and shoaling effect. At present, there are usually differences between the actual data and the results that applied classical tsunami theory to simulate tsunami propagation in the continental shelf. In the paper we analyzed and compared all kinds of shallow water wave models and numerical simulation methods, which can bring to simulate local tsunami propagation. And we propose that it maybe generate earthquake tsunami potentially on the edge of continental shelf of the East China Sea, thus needs studying tsunami propagation in the region.
