摘要:
富黏土矿物泥岩在遇水后的膨胀性是诱发多种地质灾害的关键因素之一。然而，当前对黏土矿物在泥岩膨胀过程中的微观与宏观响应机制，特别是涉及分子尺度界面作用的深入探讨仍然不足。文章采用盐离子作为“探针”，结合试验与分子动力学模拟，探究了浸水作用下关键界面在泥岩膨胀过程中的控制作用。结果表明：泥岩内部裂隙的大量产生是其发生膨胀变形的主要原因，添加盐离子后泥岩的膨胀与吸水受到相近的抑制作用；分子层面上，模拟表明盐离子抑制了蒙脱石水化过程中的层间扩展，指示了蒙脱石对泥岩膨胀的关键影响；而伊利石因其层间强相互作用与边界氢键网络形成而难以发生水化膨胀。进一步基于界面作用阐明了泥岩膨胀变形的2种界面响应机制：其一为蒙脱石分子内层间界面水化，在致密的团聚体中发生结晶膨胀而产生结构裂隙；其二为分子间微孔、裂隙界面浸润，导致泥岩内空气压缩而造成原生裂隙扩展与裂隙网络形成。研究结果可为进一步深入理解涉水泥岩地层的灾变过程提供依据。
Abstract:The swelling of clay mineral-rich mudstones upon water exposure is a critical factor contributing to various geological hazards. However, there remains a lack of in-depth investigation into the microscopic and macroscopic response mechanisms of clay minerals during the swelling process of mudstones, particularly at the molecular scale. This study employs salt ions are as a “probe”, integrating experimental methods and molecular dynamics simulations to investigate the role of key interfaces in controlling the swelling process of mudstone under water immersion. Results indicate that the formation of numerous internal cracks within the mudstone is the primary cause of its swelling and deformation. The addition of salt ions exerts a similar inhibitory effect on both the swelling and water absorption of the mudstone. At the molecular level, simulations reveal that salt ions suppress the interlayer expansion during the hydration process of montmorillonite, highlighting the crucial role of montmorillonite in mudstone swelling. In contrast, illite resists hydration swelling due to strong interlayer interactions and the formation of a boundary hydrogen-bond network. Furthermore, two interfacial response mechanisms underlying mudstone swelling and deformation are elucidated: (1) hydration of intramolecular interlayer interfaces of montmorillonite, which generates structural cracks through crystalline expansion within dense agglomerates; and (2) infiltration at intermolecular micropore and crack interfaces, leading to air compression within the mudstone, which causes primary crack expansion and the formation of a crack network. This study provides a foundation for advancing the understanding of catastrophic processes associated with water-related mudstone strata.
