中文摘要： 项目在对工业致污粘性土开展一系列宏观物理力学试验、微观结构和物理化学分析的基础上，结合现代土力学、物理化学和多孔介质理论研究粘性土在遭受工业污染物侵入后其工程性质演变的微观机制，建立考虑粘土与污染物相互作用的工业致污粘性土工程性质定量分析与评价方法。课题主要围绕以下几方面进行研究：①粘性土在工业污染物侵入后工程性质变化规律；②粘性土在工业污染物侵入后矿物及化学成分变化分析；③粘性土在工业污染物侵入后微观结构变化规律；④两种不同污染成分间相互作用研究；⑤工业致污粘性土工程性质定量分析与评价方法。该项目的开展对于丰富和发展污染土力学理论，指导工业致污粘性土的环境岩土工程实践具有重要的科学意义。 中文主题词： 工业污染；粘性土；工程性质；演变；微观机制 英文摘要: Based on a series of macroscopic physical and mechanical experiments, microstructural and physico-chemical analysis, the project is making research on the micromechanism of engineering property evolution of different kinds of industrial contaminated clayey soils by means of modern soil mechanics, physical chemistry and porous media theory, and trying to put forward a scientific method in consideration of the clay-contaminant interaction to quantitatively analyze and evaluate the engineering property of industrial contaminated clayey soils. Main research contents of the project are listed as follows: (1) engineering property variation of clayey soils when polluted by industrial contaminants; (2) variation analysis of minerals and chemical compositions in clayey soils when polluted by industrial contaminants; (3) microstructural change of clayey soils when polluted by industrial contaminants; (4) interaction between different contaminants; (5) scientific method to quantitatively analyze and evaluate the engineering property of industrial contaminated clayey soils. The project will be of great significance to not only the enrichment and development of theory of contaminated soil mechanics but also the environmental geotechnical engineering practice of industrial contaminated clayey soils. 英文主题词： industrial contamination; clayey soil; engineering property; evolution; micromechanism |
