Optimization of the Prestress Value for Multi-Row Anchor in Anti-Slide Pile Based on a Staged Orthogonal Design

Year: 2025

Type: article

Abstract: The anti-slide pile with multi-row prestress anchor is widely used to prevent the failure of the slope. This paper proposes a multi-row anchor prestress optimization method based on a staged uniform design that combines FLAC3D 9.0 numerical simulations with the minimum bending moment criterion. By determining a global reference prestress and performing successive layered adjustments, the proposed method effectively controls the peak bending moment of the support structure and significantly enhances overall stability. Case studies demonstrate that this method reduces the peak bending moment of piles by approximately 31.88%, leading to a more uniform bending moment distribution, improved safety, and better cost efficiency. These results indicate that the proposed method provides an efficient and reliable approach for optimizing prestress distribution in complex slope support systems.
