英文摘要	On the basis of the results of experiment on hydraulic properties, mechanical index and wind tunnel about reconstituted samples going through dry-wet circulation after being mixed with different content of common salt Na2SO4 and NaCl, the relationships between disintegration velocity, compressive strength, shearing strength of those samples and types and amounts of salts were studied. And then, the relationship between microstructure characteristics parameters and types and amounts of salts were researched based on microstructure analysis results of samples. At last, through the method of statistical analysis, the relationship between macro-parameters and micro-structure characters was confirmed, and the regression equations were built. The results show that the coupled action takes effect on process of earthern ruin's degradation by changing its microstructure. Above methods provide micro basis for ruin's state of degradation evaluation.
