摘要
分析了温度效应对粘性土介质若干基本力学特性的影响。对粘性土的热固结问题、温度对粘性土介质渗透特性的影响、粘性土中的热传导规律及热阻抗特性、土-水体系在温度效应下的作用机理、温度作用下粘性土的本构规律等进行了深入研究。特别就温度诱致的孔隙水压力的变化机理及不同性质土类粘性土体积变化的可逆性问题进行了探讨。
Temperature effects on mechanical characteristics of clay soils are analyzed. Some problems are studied in detail, including the thermal consolidation problem, the temperature effects on permeability, thermal conductivity and thermal resistivity, thermal volume change of the clay-water system, etc. Particularly, the changes of pore pressure induced by temperature and the mechanisms of reversibility of the thermal volume change on various types of clay soils are analyzed. Besides, the thermal mechanical models for saturated clays are discussed simply.
