Searching for Slip Surface of Disturbed Slope Based on Logistic Function by Yalin Zhu, Xuefeng Peng, Kun Tan, Ming Shi, Yin Hong, Yixian Wang

“…The related parameters (M, A, and K) are derived by the threshold, symmetry, and precision control of its function. Logistic function constructs the slip surface and compares it with the broken-line slip surface; the numerical results show that the slip points on the two slip surfaces are consistent, indicating that the logistic function fits the curve correctly; the logistic function smooths the original polyline curve, which facilitates solving the direction vector of the curve.…”
