Evaluation Method of Highway Plant Slope Based on Rough Set Theory and Analytic Hierarchy Process: A Case Study in Taihang Mountain, Hebei, China

The material foundation of soil and water conservation is built on the integrity highway plant slope. proportional relevance components that affect slope quality was evaluated based an environmental assessment actual characteristics A system four major indexes twelve secondary comprising traits, geometric factors, hydrological conditions, vegetation conditions developed to assess stability roadway slopes. rough set theory approach analytic hierarchy process were used solve weights evaluation indexes. Based a process, model proposed. eliminates inconsistency uncertainty in factors are calculate study conducted China. Taihang Mountain Hebei province using after dividing into grades. According results, can be as reference provide technical help prevent lower safety accidents. predict plants, demonstrating efficacy reliability methodology approach.
