DEVELOPMENTS IN RESEARCHES ON TIME-DEPENDENT BEHAVIOR OF SALT ROCK AND LONG-TERM STABILITY OF SALT CAVITY

  • 摘要: 介绍了地下盐腔长期运营过程中盐腔收敛变形和有效容积丧失等问题, 从盐岩流变实验研究、盐岩流变本构关系建模、盐腔长期稳定评价等方面综述了盐岩流变学研究进展. 文章指出, 将盐岩流变本构模型与流变过程中盐岩微细观尺度上的损伤演化物理机制相融合, 是盐岩流变学一个值得关注的研究方向.

     

    Abstract: A modeling approach to the time-dependent behavior of salt rock is of special interest for many underground engineering such as underground storage of natural gas and crude oil, a permanent repository of CO_2 and high-level radioactive nuclear wastes. With respect to the large deformation and even loss of effective storage volume of salt cavities in long-term service, the developments in researches on time-dependent behaviors of salt rocks are reviewed in this paper, including creep experimental studies, creep constitutive relations of salt rock and long-term stability of salt cavity. It is pointed out that the combination analysis of creep constitutive relation modeling and physical mechanism of damage growth in salt rock at the micro- and meso- scales is an attractive topic in rheology of salt rock.
