NSF Post-Earthquake Geotechnical Reconnaissance Working Group

记录和汇编从世界各地重大地震事件中吸取的主要经验教训，有助于推动岩土地震工程的研究和实践。目前的许多设计程序都是基于经验方法，随着重要案例的出现，这些方法需要重新评估和更新。然而，大地震产生的许多数据和信息都很容易腐烂，因此必须在地震发生后几天或几周内收集。这一行动是为了支持地震后岩土勘察工作组的成立，这是一个由具有震后岩土勘察经验的研究人员组成的小型工作组。该工作组的活动将在很大程度上依赖于电信和互联网的使用--如电话会议、电子邮件和在网站上张贴信息；但它也将每年举行两次会议，进行面对面的讨论。此外，GeoRecon工作组将从一个基础广泛的咨询小组、一大批杰出的岩土工程师、地震工程师和相关领域的科学家以及属于也积极参与震后勘察的组织的人员那里获得指导。GeoRecon活动将扩大、多样化和培训新一代岩土工程师在地震后勘察和从此类地震中学习。NSF还将考虑能够有效促进震后侦察的新技术和新技术，如GPS(全球定位系统)、机载LIDAR(光探测和测距)和卫星SAR(合成孔径雷达)。NSF定期支持岩土地震工程师，并单独支持海啸海岸工程师，他们已经自组织起来，组成了有效的震后和海啸后勘察小组。地质勘察工作组的目标是更好地界定这些活动，并更有效地与也参加震后侦察访问的其他小组和组织联系。例如，地震工程研究所(EERI)和美国地质调查局(USGS)是积极参与地震后调查的其他组织。这些组织各有其特定的使命，但并不侧重于岩土问题。过去的岩土勘察团队与其他勘察团队进行了有效的互动和合作，预计随着GeoRecon工作组的成立，这种互动将更加有效。此外，GeoRecon活动将成为其他学科在自然灾害发生后立即捕获的宝贵数据的典范。通过与也制定了有效程序的其他专业人员合作，并与其他社区分享这项研究的结果，对自然灾害影响的记录将得到全面改进。

Documenting and compiling the key lessons learned from major earthquake events around the world contributes significantly to advancing research and practice in geotechnical earthquake engineering. Many of the current design procedures are based on empirical methods that require re-evaluation and updating as important case histories emerge. However, much of the data and information generated by major earthquake is perishable and therefore must be collected within a few days or weeks of the occurrence of the earthquake.This action is to support the formation of the Post-Earthquake Geotechnical Reconnaissance (GeoRecon) Working Group, a small working group of researchers with experience in post-earthquake geotechnical investigations. The activities of this working group will rely heavily on telecommunication and Internet usage - such as teleconferences, e-mail, and posting to web sites; however it will also meet twice a year for face-to-face discussions. In addition, the GeoRecon Working Group will receive guidance from a broad-based Advisory Panel, a larger group of prominent geotechnical engineers, earthquake engineers and scientists in related fields, and personnel belonging to organizations that also actively participate in post-earthquake reconnaissance. The GeoRecon activity will broaden, diversify, and train a new generation of geotechnical engineers in post-earthquake reconnaissance and learning from such earthquakes. It will also consider new technologies and techniques that can effectively contribute to post-earthquake reconnaissance, such as GPS (Global Positioning System), Airborne LIDAR (LIght Detection And Ranging), and satellite SAR (Synthetic Aperture Radar).NSF has regularly supported geotechnical earthquake engineers, and separately, tsunami coastal engineers, who have self-assembled to form effective post-earthquake and post-tsunami reconnaissance teams. The goal of the GeoRecon Working Group is to better define these activities, and to interface more effectively with other teams and organizations that also participate in post-earthquake reconnaissance visits. For example, the Earthquake Engineering Research Institute (EERI), and the US Geological Survey (USGS) are other organizations that actively engage in post-earthquake investigations. These organizations each have a particular mission; but do not focus on geotechnical issues. Past geotechnical reconnaissance teams have interacted and collaborated effectively with other reconnaissance teams, and it is expected that this interaction will be more effective with the formation of the GeoRecon Working Group.Moreover, the GeoRecon activity will serve as a model for other disciplines regarding the valuable data that can be captured immediately after a natural hazard. By joining with other professions who have also developed effective procedures and sharing the results of this research with other communities, documentation of the effects of natural hazards will improve overall.
