英文摘要	Based on the environmental monitoring data and the analysis of the soluble salt content and distribution to several typical ruins during the process of winter snowfall in the plateau region, wind tunnel, disintegration, elastic wave velocity and shearing experiments in laboratory on remodeling sample mixed with the mass fraction of 0.2%-1% of anhydrous sodium sulfate and sodium chloride and through the freeze-thaw cycle after desalination were studied, to reveal the change rule of properties and essential reasons on those with the joint function of salinized and freezing and thawing, which characterizes the ability of ruins to resist wind erosion, rain erosion and indexes of strength. And then inner link between the forming processes of typical diseases such as detachment of bottom undercutting, surface crust and collapses was analyzed and explained. The results show that the ability of ruins to resist wind erosion, rain erosion and indexes of strength have significant deterioration response to coupling processes, which has non-linear attenuation law as mixing different typed and content of salt. In addition, the deterioration of related properties provides precondition and basis for the development of typical diseases. © 2016, Central South University of Technology. All right reserved.
