摘要
Abstract
The design of transmission line foundations on collapsible loess sites presents significant challenges due to the complex interactions among soil collapsibility and softening,non-uniform settlement,and dynamic loading.This study investigates the progressive damage mechanism at the foundation-soil interface in collapsible loess environments by developing a water-mechanical coupling constitutive model and performing detailed finite element simulations.To enhance design reliability and efficiency,a multi-objective optimization approach for safety factors based on reliability theory is introduced,and the proposed method is validated through in-situ testing.The research establishes a theoretical framework that effectively balances structural safety and economic feasibility for transmission line foundation design in collapsible loess regions,addressing the fundamental inconsistency between conventional static safety factors and the dynamic behavior of collapsible soils.关键词
