基于BIM+GIS的山区公路路线选线优化与地质灾害风险评估研究OA

Addressing the problems that traditional mountain highway route selection methods find it difficult to comprehensively obtain and utilize spatial geological information and cannot effectively predict geological disaster risks,this article constructs a building information modeling-geographic information system(BIM-GIS)integrated technology framework,proposes a method for determining route selection factor weights based on the Analytic Hierarchy Process and a multi-objective optimization model,and establishes a geological disaster susceptibility evaluation index system and risk classification method.The results show that this method can effectively avoid high-risk geological areas,reduce disaster losses,and provide a reference for scientific decision-making in mountain highway planning.
