【Abstract】 ∵ Basedon thecommercial software MATLAB，the wave force data in shalow water areobtained and imported into ABAQUSLoad Adding Module of large-scale finite element software inthe formof external table loads. Combined with the numerical simulation of elastic-plastic finite element，the study explores the influence of wave period，wave height and water depth on the calculation results，soas to preliminarily clarify the mechanismof instability and sliding of submarine slopes under the action of nonlinear wave loads.

【Key words】：submarine slope stability；nonlinear wave pressure；shallow water;wave action

海底斜坡失稳是主要的海洋地质灾害之一，尤其我国拥有广阔海域和长海岸线，其潜在威胁不容忽视[～2]。（剩余4411字）
