依据Prandtl机构，提出了砂土地震液化后港口码头地基承载力的计算方法，并对某沉箱码头地震后的地基承载力进行了分析，结果表明：地震力作用下，砂土孔隙水压力增大，对沉箱结构的水平力增大，弯矩增大，从而使沉箱结构偏心距增大，地基水平及竖向承载力出现不足，最终沉箱结构出现向海侧的平移、转动和沉降。%Based on Prandtl institutions,puts forward the foundation bearing capacity calculation method of wharf structure after earthquake liq-uefaction,and the foundation bearing capacity of a caisson wharf structure after the earthquake are analyzed. The result shows that under the ac-tion of earthquake,sandy soil pore water pressure increases,the horizontal force of caisson structure increases,bending distance increase. To make the caisson structure eccentricity increases,vertical bearing capacity of the foundation level and insufficient. Eventually the caisson struc-ture appeared to the translation,rotation,and deposition of the sea side.
