根据最近的实验结果和分子动力学模拟，讨论了致密饱和粘土中窄间隙（<30 A (1 A = 0.1 nm)）中的水-矿物相互作用。考虑了对宏观行为的影响。提出了两个相互作用组分的混合理论。讨论了温度和化学物质的影响。然后讨论了由热负荷或化学负荷引起的吸附水从固体到流体的传质假设。热或化学作用下粘土的塑性理论是为了处理热固结和化学固结的影响而发展起来的。关键词：导电性，有效应力，环境载荷，热化塑性。
Water–mineral interaction in narrow interstices (<30 A (1 A = 0.1 nm)) in dense, saturated clays is discussed in view of recent experimental findings and molecular dynamics simulations. Consequences to the macroscopic behavior are considered. A mixture theory for two interacting constituents is developed. Effects of temperature and chemicals are discussed. A postulate of mass transfer of adsorbed water from solid to fluid fraction caused by thermal or chemical load is then discussed. Theory of plasticity of clays affected by heat or chemicals is developed to deal with the effects of thermal and chemical consolidation. Key words : hydraulic conductivity, effective stress, environmental loads, thermo-chemo-plasticity.
