西北地区夯土遗址片状剥蚀发育特征、劣化机理与保护加固
Development Deterioration Characteristics,Mechanism,and Protection of Flake Erosion in Rammed Earth Sites of Northwest China
摘要
Abstract
Based on an elaboration of the occurrence environment,deterioration characteristics,and development mechanism of flake erosion,this paper analyzes the deterioration mechanism caused by the combined effects of wetting-drying cycles and salinization,and summarizes the protection and reinforcement methods and their applicability.The results show that the three-stage development process of flake erosion‑formation,peeling,and shedding is mainly governed by the coupling of multiple factors,including water,salt,heat,and wind.Wetting-drying cycles reduce the strength of rammed earth sites by more than 70%,while water-salt migration further decreases their durability,leading to flake erosion on the surface.Current protection and reinforcement methods for flake erosion mainly include salt damage inhibition and surface reinforcement,among which chemical reinforcement is the most widely applied.However,current studies provide insufficient quantitative descriptions of the deterioration factors governing the development of flake erosion in rammed earth sites in Northwest China.The quantitative relationships among macroscopic deterioration characteristics,mechanical property degradation,and microstructural evolution remain unclear.In addition,reinforcement methods and material types are limited,and further in-depth research is urgently needed to evaluate their durability and compatibility.关键词
