裂隙岩体溶质运移模型研究

核废料的地下深部贮存、垃圾填埋造成的污水下渗、海水入侵、输油管道老化引起渗漏等诸多应用领域的发展,要求从机理、试验和模型等方面发展裂隙岩体溶质运移理论。基于裂隙岩体系统溶质运移的多尺度概念模型,分析了目前描述裂隙岩体系统中溶质运移各种数学模型的适用性和优缺点,为选取合理的数学模型求解具体的问题提供了参考依据。最后提出了需要进一步研究的问题。

Study on model of solute transport in fractured rock mass

With the evolution of many application domains ,which are involved in radioactive waste repositories, sewage infiltration of resulting from refuse filling fields, seawater intrusion and leakage arising from oil pipeline aging, it is requested that theory of solute transport in fractured rocks is developed from the mechanism, experiment and model. Multi-scale conception models of solute transport in fractured rocks system are established. Furthermore, advantages and disadvantages of different mathematical models for solute transport are analyzed in present fractured rocks systems. It provides referential foundation for selecting rational mathematical model to solve concrete problems. Finally, problems needing further research are put forward.
