Technical description. The proposed International Research Experience for Students (IRES): Coupled Geomechanical Processes and Energy Technologies - Research Experience at Ecole des Ponts Paris Tech - ENPC, France (?CGPET - ENPC?) aims to expose Georgia Institute of Technology (GT) undergraduate and graduate students to geomechanical research applied to energy technologies, immerse them in the academic culture of a leading European institution (ENPC), and inspire them in the pursuit of a scientific career to improve the sustainability and security of energy sources and production. Undergraduate and graduate students from Georgia Tech School of Civil and Environmental Engineering (GT-CEE) will complete a two-month internship at ENPC Navier Laboratory, to work on research planned and supervised by dual ENPC and GT-CEE faculty mentors. Navier Laboratory gathers world?s experts in theoretical poro-mechanics and thermodynamics, and has unique experimental, imaging and computational facilities especially adapted for geomechanics. Topics of study envisioned in this IRES involve fundamental research in the physics of thermo-hydro-chemo-mechanical coupled processes in geomaterials, multi-scale modeling of porous networks, three-dimensional image analysis and advanced numerical simulation techniques. The ?CGPET- ENPC? program will start with five teams of dual mentors, who will work on the following subjects: (1) Clay nano-poromechanics for carbon dioxide sequestration, (2) Characterization of particulate pore structures for geological storage, (3) Micro-mechanical modeling of fatigue in salt rock for Compressed Air Energy Storage (CAES), (4) Reactive fluid injection and withdrawal in rock, for oil and gas recovery and geothermal energy systems, and (5) Freeze/thaw cycles and sulfate attacks for improved cement-based buffers. Every year, a GT-CEE mentor will spend the last week of IRES participants? internship at ENPC, to work with his/her ENPC collaborator and supervise GT-CEE students? final research presentations; similarly the ENPC mentor will spend the week following the internship period at Georgia Tech. Broader description. Fundamental understanding of soil, rock and cement-based materials is needed to address society?s most pressing needs in energy production (e.g., hydraulic fracturing, geothermal systems), energy storage (e.g., CAES) and waste management (e.g., nuclear waste disposals, carbon capture). Through their engagement in a project aimed to improve energy geotechnologies, IRES participants will discover the responsibility of researchers towards their sponsors, their scientific community and society at large. Students selected for this CGPET ? ENPC program will have an international experience as part of a cohort through cultural and professional activities, and will contribute to build and maintain a global network of scholars through public research presentations at ENPC and GT, wikipage postings, academic publications, and mentoring of new IRES participants. Currently, most students enrolled in Civil and Environmental Engineering discover soil mechanics during their senior year, through the course of Introduction to Geotechnical Engineering. Activities planned before, during and after the ENPC internships will expose a broad population of GT students to geomechanical research, which will provide opportunities to inspire and attract more students in the pursuit of a scientific career. The integration of activities for faculty and undergraduate and graduate students from ENPC and GT-CEE is expected to sustain long-term collaborations between groups focusing on experimental, theoretical and numerical research in energy geomechanics. This IRES will also serve a broader effort to share knowledge, expertise and resources between Europe and the United States, and to explore new ways to initiate scientific collaborations between high-ranked education and research institutions around the world.

技术描述。建议的国际学生研究经验（IRES）：耦合地质力学过程和能源技术-巴黎理工大学的研究经验- ENPC，法国(？CGPET - ENPC?)旨在让佐治亚理工学院（GT）的本科生和研究生接触到应用于能源技术的地质力学研究，让他们沉浸在欧洲领先机构（ENPC）的学术文化中，并激励他们追求科学事业，以提高能源和生产的可持续性和安全性。来自佐治亚理工学院土木与环境工程学院（GT-CEE）的本科生和研究生将在ENPC纳维尔实验室完成为期两个月的实习，在ENPC和GT-CEE双导师的指导下进行计划和研究。纳维实验室聚集世界？美国的理论孔隙力学和热力学专家，拥有独特的实验、成像和计算设施，特别适合于地质力学。研究课题包括岩土材料热-水-化学-力学耦合过程的基础物理研究、多孔网络的多尺度建模、三维图像分析和先进的数值模拟技术。的吗?CGPET——ENPC ?项目将从五组双导师开始，他们将研究以下主题：(1)用于二氧化碳封存的粘土纳米孔隙力学；(2)用于地质封存的颗粒孔隙结构表征；(3)用于压缩空气储能（CAES）的盐岩疲劳微观力学建模；(4)用于油气采收和地热能源系统的岩石反应性流体注入和提取；(5)用于改进水泥基缓冲液的冻融循环和硫酸盐侵蚀。每年，一名GT-CEE导师将在IRES参与者的最后一周？在ENPC实习，与他/她的ENPC合作伙伴一起工作，并监督GT-CEE学生？最后的研究报告；同样，ENPC导师将在乔治亚理工学院实习后花一周时间。解决社会问题需要对土壤、岩石和水泥基材料有基本的了解。中国在能源生产（如水力压裂、地热系统）、能源储存（如CAES）和废物管理（如核废料处理、碳捕获）方面最迫切的需求。通过参与旨在改善能源地球技术的项目，IRES参与者将发现研究人员对其赞助商，其科学界和整个社会的责任。参加本次高考的学生？ENPC计划将通过文化和专业活动获得国际经验，并将通过ENPC和GT的公开研究报告，维基发布，学术出版物以及对新IRES参与者的指导，为建立和维护全球学者网络做出贡献。目前，大多数土木与环境工程专业的学生都是在大四的时候通过岩土工程导论的课程来学习土力学的。在ENPC实习之前，期间和之后计划的活动将使更多的GT学生接触到地质力学研究，这将为激励和吸引更多追求科学事业的学生提供机会。ENPC和GT-CEE的教师、本科生和研究生活动的整合有望维持能源地质力学实验、理论和数值研究小组之间的长期合作。该IRES还将为欧洲和美国之间分享知识、专业知识和资源提供更广泛的努力，并探索世界各地高排名教育和研究机构之间开展科学合作的新途径。
