U.S.-Taiwan Workshop on Soil Liquefaction: Lessons Learned from Chi-Chi Earthquake

这一行动是为了支持美国-台湾土壤液化研讨会，重点是从1999年台湾集集地震（Mw = 7.6）中吸取教训，并建立一个网站，供研讨会前后分享信息和讨论。 该研讨会将于2003年11月在台湾举行，由台湾国家科学理事会（NSC）和美国国家科学基金会（NSF）共同资助。集集地震在台湾中西部引发了广泛的土壤液化。 它还提出了重要的研究问题，需要解决，以提高知识的岩土地震工程。 台湾有一个广泛的地震仪器系统，提供了70个三分量记录的强烈地面运动在20公里的主要故障。 关于集集地震的重要问题是明显异常的地面运动，以及它对液化的影响。 在广泛的土壤液化，特别是在粉土和砾石土中获得了重要的数据。台湾和美国的政府和工业研究机构支持了与集集地震有关的岩土地震工程问题的研究活动。 本次研讨会为台湾和美国的研究人员提供了一个讨论和分享地震知识的平台，利用互联网资源为研讨会前后的信息传播提供了有效的途径，并加强了研究与教育相结合的整体主题。 研讨会的网站将是有价值的研讨会参与者，研究人员和工程师，以及对岩土地震工程感兴趣的教育工作者和学生。

This action is to support a U.S.- Taiwan workshop on soil liquefaction, with an emphasis on learning from the 1999 Chi-Chi, Taiwan earthquake (Mw = 7.6), and to develop a web site for pre- and post-workshop information sharing and discussions. The workshop, to be held in Taiwan, November 2003, is jointly supported by the National Science Council (NSC) for Taiwan and the National Science Foundation (NSF) for the U.S.The Chi-Chi earthquake triggered extensive soil liquefaction in Central Western Taiwan. It also raises important research questions that need to be addressed in order to advance knowledge in geotechnical earthquake engineering. Taiwan has an extensive seismic instrumentation system that provided 70 three-component recordings of strong ground motion within 20 km of the main fault. Significant issues regarding the Chi- Chi earthquake are the apparently anomalous ground motions, and its implications regarding liquefaction. Significant data was obtained in the extensive liquefaction of soils, particularly in silty and gravelly soils.Government and industrial research agencies in Taiwan and the U.S. have supported activities to study the geotechnical earthquake engineering issues related to the Chi-Chi earthquake. This workshop offers a forum for researchers from Taiwan and the U.S. to discuss and share the knowledge learned from this earthquake.The utilization of Internet resources provides an effective way for pre- and post-workshop distribution of information and enhances the overall theme of the integration of research and education. The workshop web site will be of value to the workshop participants, researchers, and engineers, and to the educators and students who are interested in geotechnical earthquake engineering.
