Abstract: In order to improve the calculation method of soil pressure on retaining walls under earthquake action, a calculation formula for seismic active soil pressure on unsaturated retaining walls under steady-state seepage conditions was derived based on the variational method and limit equilibrium method. The rationality of the formula in this paper was verified by comparing the calculated values with existing results. And the influence of fitting parameters and seismic coefficients on the active earth pressure coefficient was analyzed through numerical calculations in Matlab. The results showed that the active earth pressure coefficient decreased with the decrease of fitting parameter α value and gradually approached a fixed value; The increase in both vertical and horizontal seismic coefficients will lead to an increase in the active earth pressure coefficient. The research results have certain reference value for the development of unsaturated seismic active earth pressure.
