OPTIMAL DESIGN METHOD AND SYSTEM FOR SLOPE REINFORCEMENT WITH ANTI-SLIDE PILES
The present disclosure provides an optimal design method and system for slope reinforcement with anti-slide piles. The method includes: modeling a slope type to obtain a three-dimensional (3D) slope numerical calculation model; establishing different numerical calculation models for anti-slide piles according to different reinforcement schemes of the anti-slide piles; determining optimization indexes through a coupling analysis of the 3D slope numerical calculation model and the anti-slide pile numerical calculation model; calculating a comprehensive optimization value according to the optimization index; determining an optimal anti-slide pile reinforcement scheme according to the comprehensive optimization value, and determining whether the optimal anti-slide pile reinforcement scheme meets the optimization objective; and carrying out slope reinforcement according to the optimal anti-slide pile reinforcement scheme if yes. The present disclosure establishes a multi-objective comprehensive optimization model including an optimization index system and comprehensive weights of optimization indexes. The optimization index system comprehensively reflects the stability of a slope and the safety of an anti-slide pile, and the comprehensive weights of optimization indexes are determined by a subjective analytic hierarchy process (AHP) and an objective entropy method, making an optimization result more scientific. Determine a type of a slope to be reinforced with anti-slide piles and an optimization objective Model the type of the slope to obtain a three-dimensional (3D) slope numerical calculation model Establish different numerical calculation models for anti-slide piles according to different reinforcement schemes of the anti-slide piles Determine optimization indexes through a coupling analysis of the 3D slope numerical calculation model and the anti-slide pile numerical calculation model, the optimization indexes including factor of safety, bending moment, shear force and deflection of the anti-slide piles Calculate a comprehensive optimization value according to the optimization index Determine an optimal anti-slide pile reinforcement scheme according to the comprehensive optimization value, and determine whether the optimal anti-slide pile reinforcement scheme meets the optimization objective Carry out slope reinforcement according to the optimal anti-slide pile reinforcement scheme
