| 英文摘要 | Stability assessment of anti-dip bedding rock slopes (ABRSs) remains a troublesome issue especially when there are hundreds or thousands of rock layers. The adaptive moment estimation (Adam) algorithm proposed in recent years has been widely used in artificial intelligence research and is a powerful tool for solving the above-mentioned problem. In this work, the limit equilibrium method (LEM) is combined with the Adam algorithm (referred to as the LEM-Adam method) to determine the failure surface of an ABRS undergoing shearing-flexural toppling failure. Two tests reported in previous studies (a 1 g model and a centrifuge model) were analyzed to validate the LEM-Adam method. The critical failure surface and the safety factor agree well with the experimental observations, validating the LEM-Adam method in the stability analysis of ABRSs. Finally, the LEM-Adam method was compared with the LEM combined with a genetic algorithm (GA). The results show that the LEM-Adam method has higher computational efficiency and eliminates the randomness of the solution. The LEM-Adam method proposed in this work offers a practical and fast approach for the stability analysis and design of ABRSs. |
