英文摘要Finding the failure surface and analyzing the stability of an anti-dip bedding rock slope (ABRS) with the potential of block-flexure toppling failure are still a troublesome issue. In this work, we combine force-transfer model (FTM) and Adaptive Moment Estimation method (Adam) to propose a new approach called FTM-Adam method for analyzing the stability of ABRSs. The results of a centrifuge test and 4 UDEC models are used to verify the feasibility of this method. Moreover, a comparison of the FTM-Adam and FTM-GA is carried out. The results show that the FTM-Adam can efficiently find the failure surface and the corresponding safety factor of ABRSs. The comparison between the results of FTM-Adam and the simulation results shows that the RMSE of the failure surface (represented by the artificial design variables) is 0.2198, and the deviation of the safety factor is 5.39%, which is sufficient for the application in practice. Results show that the efficiency of the FTM-Adam method is 30 times higher than that of FTM-GA. The main limitation of the FTM-Adam method is that the choosing of the initial failure surface has inevitable influence on the final optimization result. An inclined plane located 10 degrees-20 degrees above the normal plane to the continuous joints is suggested to be the initial failure surface according to previous observations.
