Method and system for analyzing the stability of high slopes with Anti-sliding piles

Abstract

The invention belongs to the technical field of geotechnical engineering and geological disaster prevention and control, and discloses a method and system for analyzing the stability of high slopes with anti-sliding piles. The method includes: determining the position of an initial sliding surface based on topographic parameters, coordinates of the sliding surface and slope surface, physical and mechanical parameters of soil mass and parameters of anti-sliding piles; calculating the landslide thrust acting on the anti-sliding piles based on the determined position of the initial sliding surface; determining the position of the rotation center point of the anti-sliding piles based on the landslide thrust acting on the anti-sliding piles; conducting stability review and iterative decision-making based on the position of the rotation center point of the anti-sliding piles; calculating the maximum lateral earth pressure of a single pile after the completion of stability review and iterative decision-making; and calculating the stability of the soil mass in front of the piles based on the maximum lateral earth pressure of the single pile. The system corresponding to the method includes an initialization module, a landslide thrust calculation module, a center point position calculation module, an iteration module, a lateral earth pressure calculation module and a stability calculation module, which implement the above steps in a one-to-one correspondence manner. The invention integrates slope stability, pile force and local stability into a unified analysis framework with logical judgment, distinguishes different failure modes by introducing the concept of a rotation center, and realizes semi-automation of analysis-design-optimization through an embedded iterative process, which greatly improves the efficiency and reliability of stability analysis of high slopes with anti-sliding piles.
