U. S. Participation in ROCKSITE and Indo-U.S.-Norweigian Workshop on Field Methods in Geomechanics

这一行动是为了支持美国研究人员参加1999年12月6日至8日在印度班加罗尔举行的用于场地表征的岩石工程技术国际会议(ROCKSITE)，以及参加1999年12月9日至10日在印度班加罗尔举行的印度-美国-挪威关于地质力学现场方法的研讨会。ROCKSITE会议由印度国家岩石力学研究所(NIRM)和挪威岩土研究所(NGI)联合举办。重点是土木工程和采矿工程中用于设计开挖的岩土勘察方法和工具。在为期三天的ROCKSITE会议结束时，来自印度、挪威和美国的与会者将参加为期两天的研讨会，讨论目前用于场地表征的各种方法，并参加对印度南部正在建设的大型地下厂房洞穴皮卡拉的实地考察。两次会议和实地考察的总体主题是岩石野外使用表征的方法，既有目前使用的方法，也有潜在的新的创新方法。讨论围绕现场表征的三个主题进行：(1)应用于优化爆破块度，(2)应用于地面和地下稳定性设计，以及(3)应用于流体在岩体中的流动。最后，皮卡拉发电厂项目的实地考察将讨论与该场地有关的现场表征问题。预计这些会议将加深对岩体表征方法的理解。将建立一个万维网，以记录研讨会的成果，并鼓励岩石力学R&D社区对岩体表征方法进行更多和持续的讨论。

Abstract- 9910309This action is to support the participation of US researchers in the International Conference on Rock Engineering Techniques for Site Characterization (ROCKSITE), being held in Bangalore, India, 6-8 December 1999; as well as participation in the Indo-US-Norwegian Workshop on Field Methods in Geomechanics, Bangalore, India, 9-10 December 1999.The ROCKSITE conference is organized jointly by the National Institute of Rock Mechanics (NIRM) in India, and the Norwegian Geotechnical Institute (NGI) in Norway. The focus is on geotechnical investigation methods and tools for the design of excavations in civil and mining applications. At the conclusion of the three-day ROCKSITE conference, participants from India, Norway and the United States will participate in the two-day workshop to discuss the various methods currently being used for site characterization, and participate in a field trip to the large underground powerhouse cavern, Pykara, being constructed in Southern India.The overall theme for both meetings and the field trip is the methods for field-use characterization in rock masses, both those currently in use, as well as potentially new innovative methods. The discussion is planned around three topics in field site characterization: (1) application to optimizing blast fragmentation, (2) application to surface and underground stability design, and (3) application to fluid flow through rock masses. Finally, the field trip to the Pykara Powerhouse Project will address field characterization issues involved with this site.It is expected that these meetings will develop a better understanding of rock mass characterization methods. A World Wide Web site will be established to document the workshop findings and to encourage additional and continued discussion of rock mass characterization methods by the rock mechanics R&D community.
