摘要
[目的]研究枯枝碎屑对吹填土脱盐及理化性质的影响.[方法]采用室内土注淋洗模拟脱盐试验,设不添加枯枝碎屑(CK)、添加土柱体积5％的枯枝碎屑、添加土柱体积10％的枯枝碎屑,研究枯枝碎屑的脱盐效果.[结果]添加枯枝碎屑有利于加快吹填土盐峰形成、下移和消失,且随着枯枝碎屑添加量的增加而加快,脱盐碱化特征明显高于CK.[结论]枯枝碎屑可应用于吹填土脱盐.
Abstract
[Objective] To study effects of wood chips on desalination of dredger fill and physicochemical properties.[Method] The desalting experiment was simulated by indoor soil column leaching.Setting up three treatments including blank control,adding soil column volume 5％ wood chips,adding soil column volume 10％ wood chips,the desalination effect of dredger fill was studied.[Result] The results showed that the addition of wood chips was beneficial to accelerate the formation,descent and disappearance of the salt peaks,but their alkalization characteristics were significantly higher than those without adding wood chips treatment.[Conclusion] Wood chips can be applied in desalination of dredger fill.
