摘要

摘要:本文总结了美国国家科学基金会主办的近地表地热能热活动岩土系统研讨会的主要成果。2013年3月,来自世界各地的55名研究人员聚集在瑞士洛桑,参加了为期3天的研讨会,讨论岩土工程与近地表地热能之间联系的现状。本文概述了热活动岩土系统中材料表征的最新进展,以及我们对这些系统的热学和热力学行为的理解。本文还包括对可用的热学和热机械设计方法的回顾,以及从热活性系统的实施中获得的相关经验教训。对岩土工程和近地表地热能之间的界面新兴技术的讨论表明,在不同领域之间有许多知识转移的机会。在研讨会期间确定的当前挑战和未来相关研究议程清单表明,许多重要挑战已经克服,但仍有重要问题需要解决。

Outcomes from international workshop on thermoactive geotechnical systems for near-surface geothermal energy: from research to practice
Abstract This paper summarizes the main outcomes of an NSF sponsored workshop focused on thermoactive geotechnical systems for near surface geothermal energy. A group of 55 researchers from around the world gathered in March 2013 for a 3 day workshop in Lausanne, Switzerland to discuss the current status of the linkages between geotechnical engineering and near surface geothermal energy. This paper provides a summary of the state of the art in characterization of materials in thermally active geotechnical systems, as well as our understanding of the thermal and thermomechanical behavior of these systems. The paper also includes a review of available thermal and thermomechanical design methods, along with associated lessons learned from implementation of thermally active systems. A discussion of the emerging technologies at the interface between geotechnical engineering and near surface geothermal energy indicates that there are many opportunities to transfer knowledge between different fields. A list of current challenges and the associated research agenda for the future identified during the workshop indicates that many important challenges have been overcome but there are still important issues that need to be solved.
