我校理学院孔亮教授领衔的“岩土力学与海洋岩土工程”团队在海洋能源土(含天然气水合物的海洋沉积土)力学特性研究方面取得重要进展,2025年1月以来,团队连续在《Acta Geotechnica》《Earth-Science Reviews》《Ocean Engineering》等重要期刊发表论文6篇(SCI一区4篇,二区2篇)。孔亮教授指导的博士生桑松魁、赵亚鹏与硕士生曾照圆为第一作者,孔亮教授为通讯作者。
6篇论文均围绕我国南海北部水合物成矿区典型的泥质粉砂型能源土力学特性,开展了室内试验、本构模型与数值模拟等研究。研究成果揭示了水合物开采过程中能源土的力学响应机制与工程地质风险演化规律,不仅深化了对深海能源土力学行为的科学认识,而且对推进我国海洋天然气水合物商业化试采进程具有重要的参考价值。
发表在《Earth-Science Reviews》的综述论文从实验调查、数值模拟及理论建模三个方面系统总结了海洋能源土力学特性研究的最新进展,揭示了微观机理,明晰了未来挑战,并提出了针对性的建议。发表在《Geomechanics for Energy and the Environment》的综述论文从海洋能源土的微观结构类型、离散元素模拟方法、微观力学特性与水合物分解微观多场耦合离散元模拟等方面进行了综述和总结,讨论了当前能源土微观力学特性研究中存在的不足与挑战,并提出了相应的建议。

发表在《Acta Geotechnica》《Ocean Engineering》《Soil Dynamics and Earthquake Engineering》的论文对我国南海北部水合物成矿区典型的层状泥质粉砂型能源土开展了系列室内三轴试验研究,获得了有效围压、黏土含量与水合物饱和度对其力学与变形特性的影响规律,并分析与探讨了相应的力学机理。发表在《Gas Science and Engineering》的论文采用5因素和5水平的正交试验,进行了有效围压、孔隙压力、饱和度、细粒含量和粘土含量对能源土强度、模量等力学参数的敏感性分析。

孔亮教授团队自2011年切入我国天然气水合物试采研究领域以来,十多年坚持不懈,瞄准国家“双碳”战略需求,围绕深海能源土力学特性与水合物成矿区海底地质灾害模拟评估开展研究。团队获批自然资源部重大专项子课题1项(147万元),连续获批国家自然科学基金面上项目5项,指导青年教师获批国家自然科学基金青年项目7项,山东省自然科学基金项目9项。此外,团队发表SCI、EI论文69篇,授权发明专利10件,培养的研究生有1人获山东省优秀博士论文,1人获山东省优秀硕士论文。(撰稿:牛庚,赵世军;审核:初鹏程)
