摘要: 水化学环境变异对黏土力学特性具有很重要的影响。分别从物理力学试验分析和理论描述2个方面论述了水化学环境变异对黏土力学特性影响这一方向课题的研究现状。通过分析归纳可知目前对于以蒙脱石含量为主的膨润土的研究较为透彻, 得出了较为一致的规律并且揭示了其影响机理;对于高岭土和一般性黏性土在水化学环境变异下的响应规律揭示不清, 机理阐明不清, 需要进行系统完整的试验研究;同时, 目前的土力学理论框架难以考虑水化学变异的影响, 需要建立新的能考虑化学-力学耦合的土力学理论框架。最后, 总结这一研究方向亟待解决的科学问题和后期的发展前景。

Abstract: Hydrochemical environment variation has significant influence on the mechanical properties of clays. The research status of the influence of hydrochemical environment variation on the mechanical properties of clays is presented from aspects of test analysis and theoretical description of physical mechanics test. Summaries and analysis show that the regularity and mechanism of hydrochemical environmental variation affecting on mechanical properties of bentonite containing mainly smectite have been understood clearly. However, for kaoline and common clays, systematic and complete tests and analysis are needed to reveal the regularities and interaction mechanisms. Besides, a new theory frame in consideration of the interaction between chemistry and mechanics is needed since the current soil mechanics theory is difficult to describe the influence of hydrochemical variation on mechanical properties of clay. Finally, scientific problems need to be solved urgently and the development prospects of this research direction are summarized.

Key words: rock and soil media, hydrochemical environment, chemo-mechanical coupling, mechanical response
