| Abstract: | In this paper, a penalty function method for solving non-linear optimization problems was introduced to obtain a reliability indicator and to calibrate the partial factors, avoiding the complexity associated with the calibration process of the partial factors and maintaining the accuracy of the reliability indicator. The proposed method was employed to calibrate the partial factors of gravity dam sliding stability analysis. The results indicate that using the penalty function-based calculation method to determine the reliability indicator not only ensures correctness and accuracy but also makes the calibration process of partial factors simple and easy to perform. |
