摘　　要：在长期自然因素和人为因素的作用下,黄土中含盐量发生变化,使得土的力学性质发生改变。文中通过自主研发一种水平方向的去易溶盐淋洗装置,开展黄土室内淋溶试验,结果表明该装置能有效去除土体试样中的易溶盐成分;同时提出一种能测量黄土试样淋溶变形的试验方案。Under the long-term influence of natural and human factors,the salts content in the loess change inevitably,which brings about the variation of mechanical characteristics.In this study,a kind of leaching device for soluble salts with horizontal direction was developed and used for the indoor leaching test of loess.The experimental results indicate that the developed device could effectively remove the soluble salts in loess.In addition,an experimental proposal to measure the leaching deformation was also put forward in this paper.
