摘要： 珊瑚礁灰岩作为热带岛礁工程的关键地基持力层与天然建材，其特殊的生物成因背景赋予了其异于陆源岩石的力学逻辑。本文系统梳理了礁灰岩在微观结构表征、力学特性演化、多场耦合劣化及数值模型应用等方面的研究进展。在微观层面重点阐明了礁灰岩的多级孔隙结构及其数字化表征方法；在力学特性方面讨论了静载作用下礁灰岩的损伤机理及复杂海洋环境下的长期服役性能；在数值模型方面评估了二元介质本构模型在刻画礁灰岩失效过程中的适用性。综述发现，礁灰岩受生物成因驱动呈现出明显的垂直二元沉积结构，其强度受控于微观拓扑结构效应而非单一物理指标；孔隙张量理论揭示了大孔隙定向排布产生的应力集中是导致其力学参数离散的核心物理机制；礁灰岩具有显著的“起裂敏感性”，且扩容点处的侧向损伤程度通常远超轴向损伤；环境劣化研究确定了 400°C 的热损伤阈值，并证实海洋酸化导致的化学溶蚀可使岩石强度在短期内下降 48.1% 至 60.3% ；二元介质模型能有效刻画胶结破坏引发的“岩-土”过渡态，而物理信息神经网络等人工智能方法将是实现跨尺度参数精准预测的前沿路径。

Abstract: Coral reef limestone is a critical foundation layer and natural construction material for tropical island engineering. Its distinct biogenic origin results in mechanical behavior that differ significantly from those of terrigenous rocks. This article systematically reviews recent advances in microstructure characterization, mechanical behavior, multi-field degradation, and numerical modeling of reef limestone. At the micro-scale, the hierarchical pore structure and digital characterization methods are emphasized. Mechanically, the damage mechanisms under static loading and long-term performance in marine environments are discussed. Numerically, the applicability of a binary-medium constitutive model in simulating failure processes is evaluated. Key findings include: (1) Coral reef limestone​ exhibits a distinct vertical binary sedimentary structure controlled by biogenesis, with strength governed by microscopic topology rather than individual physical parameters; (2) pore tensor theory identifies stress concentration from oriented macropores as the main cause of mechanical parameter dispersion; (3) high crack-initiation sensitivity, with lateral damage at dilation points substantially exceeding axial damage; (4) a thermal damage threshold of 400°C and strength reductions of 48.1%-60.3% due to acid dissolution; (5) the effectiveness of binary-medium models in capturing rock-soil transition behavior, with physics-informed neural networks represent a frontier approach for cross-scale parameter prediction.
