中文摘要：

通过对分别掺入不同含量Na2SO4和NaCl并经历干湿循环的遗址土重塑样的基本水理、力学指标测试以及风洞试验,揭示试样在耦合作用下崩解速度、抗压强度、风蚀速率与盐分的关系;并通过微结构分析实验研究试样微结构特征参数与盐分之间的关系。进而通过统计学分析方法证实试样的宏观性质指标与各微结构特征参数间的相关关系并建立回归方程。研究结果表明：耦合作用通过改变微观结构而对遗址劣化进程产生影响,从而为遗址劣化程度的评价提供了微观依据。

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.
