中文摘要：

层状盐岩是我国深部能源（如石油、天然气等）地下储存的重要方式,研究层状盐岩中储库稳定性的影响因素对于我国能源地下储存具有重要意义.基于宏观平均意义下考虑细观弯曲效应的三维Cosserat介质扩展粘弹塑性渐进破坏本构模型,运用FLAC3D通过数值模拟方法分析了硬质泥岩夹层含量、泥岩夹层与盐岩的刚度比对层状盐岩体中能源储存库稳定性的影响,同时对层状盐岩体中能源储库的运行内压、高径比、上覆层厚度等影响因素进行了分析,这将为我国含有硬质泥岩夹层的层状盐岩体中能源储库的修建和长期运营提供现实依据.

英文摘要：

For the status that energy storage in bedded salt rocks is an important way in China, it is important to study the relevance factors affecting the stability of energy storage in laminated salt rocks. On the basis of 3 - D expanded Cosserat medium constitutive model that takes the mesotropic bending effect into account in the sense of macro average, the influences of the content of the anhydrite interlayer in laminated salt rocks and the stiffness ratio between the anhydrite and rock salt on the stability of storage in laminated salt rock formation was investigated by a new user - defined FLAC3D interface program of 3 - D expanded elasto - viscoplastic progressive failure constitutive models. Besides, the influences of the running inner pressure, the height radius ratios and the overlying thickness, are studied in detail. It give guidance to build and manage the energy storage in bedded salt rocks with the anhydrite interlayers .
