DUSEL ISRM Workshop; held in Lisbon, Portugal; July 7-13, 2007

为期一天的研讨会将于2007年7月7日在葡萄牙里斯本举行，紧接在2007年7月8日至13日召开的第11届国际岩石力学学会(ISRM)大会之前。该研讨会的目的是讨论在深部地下科学与工程实验室(DUSEL)进行岩石力学研究的可能性。DUSEL是美国国家科学基金会的一项倡议，旨在成为一个多学科的设施，用于物理、微生物学、地球科学和地球工程的研究。原位岩石的力学行为，以及它如何受到原位环境的影响，是岩石力学和岩石工程的核心问题，也是1962年成立ISRM的主要动机。由于分析和数值计算技术的进步，现在有可能将现场条件纳入岩体模型中。到目前为止，还不可能直接对照现场观测来测试这些模型的有效性。杜塞尔将是克服这一主要障碍的主要刺激因素。讲习班的目的是：(I)鼓励美国大学的研究人员为杜塞尔提出岩石力学和岩石工程实验建议；(Ii)促进国际同行之间对这些想法的批判性讨论；(Iii)建议建立一个由各种岩石类型和地层的现有地下研究实验室组成的国际网络，杜塞尔将成为其中的一部分。大多数位于岩石中或位于岩石上的工程结构都取决于岩体的强度和变形能力。对这些因素的认识不足导致了土木结构和地雷的重大灾难。这些问题包括：土木工程和资源开采项目面临的挑战越来越大；地下越来越多地用于各种用途(公共交通；石油和天然气储存；分离危险和有毒废物；二氧化碳封存等)；地下水可能未受到污染；在断层上引发意外和破坏性的地震滑动。所有这些都需要更好地了解现场岩体的性态。这次研讨会将使美国岩石力学研究界对这些问题有更多的认识。

An all-day workshop will be held on July 7, 2007, in Lisbon, Portugal, immediately before the 11th Congress of the International Society for Rock Mechanics (ISRM), July 8-13, 2007. The objective of this workshop is to discuss rock mechanics research possibilities in the Deep Underground Science and Engineering Laboratory (DUSEL). DUSEL, an initiative of the National Science Foundation, is intended as a multidisciplinary facility for research in physics, microbiology, geoscience and geoengineering.The mechanical behavior of rock in situ, and how it is affected by the in situ environment, is the central concern of rock mechanics and rock engineering, and was the primary motivation for founding the ISRM in 1962. It is now possible, due to advances in analytical and numerical computational techniques, to incorporate in situ conditions in models of the rock mass. To date, it has not been possible to test the validity of these models directly against in situ observations. DUSEL will be a major stimulus towards overcoming this major obstacle. The Workshop is intended to (i) stimulate researchers in US universities to propose rock mechanics and rock engineering experiments for DUSEL; (ii) to stimulate critical discussion of these ideas between and international colleagues; (iii) to propose an international network of existing Underground Research Laboratories in various rock types and formations of which DUSEL would be a part. Most engineering structures in or on rock depend on the strength and deformability of the rock mass. Inadequate understanding of these factors has resulted in major catastrophes in civil structures and in mines. Increasing challenges in civil engineering and resource extraction projects; greater use of the subsurface for an increasing variety of applications ( mass transit; oil and natural gas storage; hazardous and toxic waste isolation; CO2 sequestration; etc.); the potential for groundwater is not contaminated; and triggering of unanticipated and damaging seismic slip on faults. All of these demand a much better understanding of in situ rock mass behavior. This Workshop will lead to a greater awareness of these issues in the US rock mechanics research community.
