项目摘要
There is much to learn from the recent New Zealand and Japan earthquakes. These earthquakes produced differing levels of liquefaction-induced ground movements that damaged buildings, bridges, and buried utilities. Along with the often spectacular observations of infrastructure damage, there were also many cases where well-built facilities located in areas of liquefaction-induced ground failure were not damaged. Researchers are working on characterizing and learning from these observations of both poor and good performance. The "Liquefaction-Induced Ground Movements Effects" workshop provides an opportunity to take advantage of recent research investments following these events to develop a path forward for an integrated understanding of how infrastructure performs with various levels of liquefaction. Approximately 50 leading researchers in the field, two-thirds from the US and one-third from New Zealand and Japan, will convene in Berkeley. The objective of this workshop is to identify which empirical and analytical methods hold the greatest potential for advancing insight on the effects of liquefaction-induced ground movements on structures and therefore should be considered high priority for further research. The workshop will also advance the development of younger researchers through identifying research approaches that appear to be promising, as well as to promote future collaborations among participants. Simplified liquefaction-induced ground movement evaluation procedures cannot explain the different levels of liquefaction-induced infrastructure performance during recent earthquakes in New Zealand and Japan. These earthquakes with their excellent ground motion recordings, comprehensive subsurface investigations, and well-documented performances of structures, provide an exceptional opportunity to advance our understanding of the effects of liquefaction. There are not well-validated procedures available to evaluate the effects of liquefaction-induced ground movements on infrastructure. With the limitations inherent in investigating liquefaction effects solely in the laboratory or through numerical simulations, there is a pressing need to use well-documented case histories to gain insights and to develop analytical procedures for evaluating the effects of liquefaction. The quantity and quality of the ground characterization and ground failure data in the recent earthquakes are unparalleled. These events provide the opportunity for an integrated study of building and lifeline performance at a degree of detail and level of complexity that has not been realized previously. The project will support international collaborations between New Zealand, Japan, and US earthquake researchers and help young US researchers develop promising international research contacts. The interactions and information exchange among the experts will advance liquefaction engineering as well as new collaborations.
最近新西兰和日本发生的地震有很多值得我们学习的地方。这些地震产生了不同程度的液化引起的地面移动,损坏了建筑物、桥梁和埋在地下的公共设施。除了经常观察到的基础设施损坏的壮观情况外,还有许多情况下,位于液化引起的地面塌陷地区的建造良好的设施没有损坏。研究人员正在努力描述这些表现不佳和表现良好的观察结果,并从中吸取教训。“液化引起的地面移动效应”研讨会提供了一个机会,利用这些事件后最近的研究投资,制定一条前进的道路,以便全面了解基础设施在不同液化水平下的表现。大约50名该领域的顶尖研究人员将聚集在伯克利,其中三分之二来自美国,三分之一来自新西兰和日本。这次研讨会的目的是确定哪些经验和分析方法最有潜力深入了解液化引起的地面移动对建筑物的影响,因此应被视为进一步研究的高度优先事项。讲习班还将通过确定似乎有希望的研究方法来促进年轻研究人员的发展,并促进参与者之间未来的合作。简化的液化引起的地面移动评估程序不能解释新西兰和日本最近地震期间液化引起的基础设施性能的不同水平。这些地震以其出色的地面运动记录、全面的地下调查和结构的良好记录性能,为我们提供了一个极好的机会来促进我们对液化影响的理解。目前还没有经过充分验证的程序来评估液化引起的地面移动对基础设施的影响。由于仅在实验室或通过数值模拟研究液化影响所固有的局限性,迫切需要使用记录良好的案例来获得见解,并开发评估液化影响的分析方法。最近几次地震的地面特征和地面破坏数据的数量和质量都是无与伦比的。这些活动提供了对建筑和生命线性能进行综合研究的机会,其详细程度和复杂程度是以前从未实现的。该项目将支持新西兰、日本和美国地震研究人员之间的国际合作,并帮助美国年轻研究人员发展有前途的国际研究联系。专家之间的互动和信息交流将促进液化工程以及新的合作。
