| 摘 要： | 盐渍风蚀是中国西北干旱区岩土体盐渍劣化加剧风蚀损耗的一种普遍破坏效应,导致遗址体底部盐渍区掏蚀凹进,严重威胁遗址整体稳定。基于室内试验,采用脱盐遗址土掺入不同含量NaCl后制成重塑样,模拟自然干湿循环条件养护并进行声波测试和风洞试验,就遗址土盐渍劣化和风蚀损耗效应做出初步分析。结果表明:含氯盐遗址土试样盐渍劣化和风蚀损耗过程中含盐量是内在因素,干湿循环起着外助力作用。

| Abstract: | Saline wind erosion,which causes the salinized deterioration and exacerbats the loss in wind erosion for rock-mass and soil-body,is a universal damage effect in northwest arid area of China.It leads to the growth and development of undercutting and recessed footing in the earthen sites,seriously threatens the overall stability of the sites. Based on the laboratory experiments,by using remodeling samples of the site soil,which are desalted and mixed with chlorine(NaCl)in different content and then maintained... |
