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.

一个全天的研讨会将于 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 日举行的国际岩石力学学会 (ISRM) 第 11 届大会之前。本次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，旨在成为物理学、微生物学、地球科学和地球工程研究的多学科设施。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关注点，也是 1962 年建立 ISRM 的主要动机。由于分析和数值计算的进步，现在已经成为可能 技术，将现场条件纳入岩体模型中。 迄今为止，还不可能直接根据现场观测来测试这些模型的有效性。 DUSEL 将成为克服这一主要障碍的主要动力。 该研讨会旨在 (i) 激励美国大学的研究人员为 DUSEL 提出岩石力学和岩石工程实验； (ii) 激发国际同行之间对这些想法的批判性讨论； (iii) 提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，DUSEL 将成为其中的一部分。 大多数岩石内或岩石上的工程结构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矿山的重大灾难。 土木工程和资源开采项目面临的挑战日益增加；更多地利用地下进行越来越多的应用（公共交通、石油和天然气储存、危险和有毒废物隔离、二氧化碳封存等）；地下水未被污染的可能性；并触发断层上意想不到的破坏性地震滑动。 所有这些都需要更好地了解原位岩体行为。 本次研讨会将提高美国岩石力学研究界对这些问题的认识。
