干旱区土遗址盐渍带风蚀损耗效应微观机制研究
Study of microscopic mechanism of effect of aeolian erosion ullage at salinization belt on earthen ruins in arid region
摘要
Abstract
Based on salinity field observations and qualitative analysis results at salinization belt of the typical earthen ruins in the research area, the paper summarizes the characteristics of earthen ruins with saline soil and generates a brief concept of aeolian erosion ullage effect. And then, on the basis of wind tunnel simulation experiment and microstructure analysis results of reconstituted samples going through dry-wet circulation after being mixed with different content of common salts Na2SO4 and NaCI, it reveals that the saline process of those salts have significant impact on anti-erosion ability of the site, and a good correlation existing between microstructure characteristics parameters of pore and wind erosion rate of the samples under saline process is also proved by statistical analysis method. Finally, with a combination of the qualitative analysis and the experimental results, depletion mechanism of the effect of aeolian erosion ullage at the salinization belt of earthen ruins is preliminarily discussed from a microcosmic standpoint.关键词
