不同地区的盐渍土的工程特性存在着较大差异。为揭示宁夏陶灵盐台地缓坡丘陵区盐渍土的力学性能和对煤炭间接液化项目的影响，采用扫描电子显微镜分析研究该地区盐渍土的微结构对溶陷性、无侧限抗压强度特性的相互关系。结果表明盐渍土氯盐和硫酸盐含量大于30％，有的甚至超过了50％，主要以硫酸盐为主；矿物成份主要含石英、石膏、钾长石、钙长石等。
不同地區的鹽漬土的工程特性存在著較大差異。為揭示寧夏陶靈鹽檯地緩坡丘陵區鹽漬土的力學性能和對煤炭間接液化項目的影響，採用掃描電子顯微鏡分析研究該地區鹽漬土的微結構對溶陷性、無側限抗壓彊度特性的相互關繫。結果錶明鹽漬土氯鹽和硫痠鹽含量大于30％，有的甚至超過瞭50％，主要以硫痠鹽為主；礦物成份主要含石英、石膏、鉀長石、鈣長石等。

There are always big differences in engineering properties of saline soil in different regions .In order to reveal impact on liquefaction of coal project caused by the mechanical performance of saline soil in Taoling region of Ningxia area .The relationship between microstructure of saline soil and unconfined compressive strength , was investigated by using scanning electron microscope (SEM).The result shows that content of chlorine salt and sul-fate in saline soil is more than 30%, some even more than 50%; primary mineral ingredients are quartz , gyp-sum, potassium feldspar , anorthite, etc.
