中文摘要：

根据盐岩溶解机制，对盐岩裂隙的溶解过程进行合理简化和假设；在此基础上，考虑盐岩裂隙溶解和渗透性变化的耦合条件，建立盐岩裂隙渗流溶解耦合模型。利用自行设计研制的盐岩裂隙渗流-溶解耦合试验装置对特定条件下的盐岩裂隙渗流-溶解耦合过程进行试验研究，并应用盐岩裂隙渗流-溶解耦合模型进行模拟分析与验证，计算结果与试验结果非常吻合，表明所建立的盐岩裂隙渗流-溶解耦合模型可以很好地描述盐岩裂隙的渗流-溶解耦合机制。该研究成果为进一步研究盐岩的应力-渗流溶解耦合机制奠定重要的理论和试验基础。

英文摘要：

Dissolving process of salt rock crack is theoretically simplified according to the dissolution mechanism of salt rock; and coupled penetrating-dissolving model for salt rock crack is then set up by taking salt rock crack dissolution, permeability variation, and their interaction into consideration simultaneously. Experiment on coupled penetrating-dissolving process of salt rock crack is performed under certain conditions using the device for coupled penetrating-dissolving test for salt rock crack designed by the authors： and the coupled penetratingdissolving model is used to model the dissolving process under the same conditions. The computational results agree well with those obtained by experiment. The achieved results can provide an important foundation for the theoretical and experimental aspects of further analyses of coupled mechanical, penetrating, and dissolving mechanism of salt rock.
