摘要:
为查明孔隙水化学环境对Q3黄土的电阻率与其影响因素之间的相互联系,通过模拟酸碱溶液对不同压实度的Q3黄土进行污染,并利用伏安法电阻率测试装置分析不同污染类型(酸、碱)、不同含水率、不同污染浓度等在不同压实度下的黄土试样的电阻率演变特征.实验结果表明:污染黄土的电阻率随含水率增加而呈幂指数减小,含水率增加至阈值后电阻率基本恒定; 同等污染浓度下酸污染土电阻率大于碱污染土电阻率; 污染黄土的电阻率随着污染浓度、压实度增加而逐渐降低.最后基于污染土电阻率随含水率降低的幂函数模型,分别建立了酸碱污染土电阻率与含水率、污染浓度、压实度间的协同联系.试验结果可为污染黄土场地的勘察、工程评价和改造治理提供数据支撑和理论依据.
Abstract:
In order to ascertain the interaction between the resistivity of polluted remodeled Q3 loess and its influencing factors,the paper utilized a simulated acid-based solution to contaminate Q3 loess in laboratory tests,and analyzed the resistivity change of the loess samples of different compaction degree with the self-developed voltammetry resistivity test device from the aspects of the different types of pollution(Acid,alkali),different water content,different pollution concentration,etc.The results show:the resistivity of the contaminated soil decreases exponentially as the water content increases; when the water content increases to the threshold value,the resistivity change rate remains constant; the resistivity of acid-contaminated soil is greater than that of alkali-contaminated soil at the same pollution concentration.The resistivity of acid-base contaminated soil gradually decreases with the increase of pollution concentration and compaction degree.At the same time,based on the power function model that the resistivity decreases with the water content reduction of the contaminated soil,the synergy relationship formula between the resistivity of the acid-alkali contaminated soil and the water content,pollution concentration and compaction degree is established respectively.
