In this paper, the shortcoming of Sarma method, a slop safety factor calculation method based on pseudo-static method, are improved by adding real seismic force, calculating acceleration amplification coefficient of each block by using numerical simulation and drawing the time-history of safety factor by using matlab software. The dynamic Sarma method is proposed. Through the calculation of an example, the rationality of the calculation result of slope safety factor by using dynamic Sarma method is verified.
