This action is for support of a workshop whose objective is the selection of a geotechnical test site or sites for earthquake engineering research and for general geotechnical engineering research. Before the foundation of a building is excavated, the site is characterized by means of a morphological, geological, and hydrological examination. The process of exploring to characterize or define small scale properties of substrata at construction sites is unique to geotechnical engineering: In other engineering disciplines, material properties are specified during the design, or before construction or manufacture, and then controlled to meet the specification. Researchers in geotechnical engineering often require well characterized sites at which to perform experiments. Locating and characterizing these sites is very time consuming (and often too costly to justify a single inexpensive experiment) and usually the sites are used only for a single experiment. There is a need to develop well characterized and instrumented sites which are available as a national resource to increase research productivity and cooperation between research groups. The difficulty is in locating and deciding upon general purpose sites, and in planning for the maintenance, management, and long term funding of such sites. The purpose of this workshop is to address these issues, specifically to identify the best sites, define specific plans for the construction of structures and the provision of instrumentation, and prepare cost estimates for the development and operation of each site. The test sites will be used: (a) to study the phenomenon of soil response to dynamic loading, especially liquefaction, (b) to investigate: (1) the resistance of buried pipelines to earthquake shaking; (2) the seismic resistance of constructed facilities; and (3) soil-structure interaction phenomena (such as the performance of piles), and (c) to evaluate new tools for in situ testing, laboratory testing, and instrumentation . The report of the National Research Council on "Liquefaction of Soils During Earthquakes" recommends that the establishment of an experimental test site be explored.

这一行动是为了支持一个讲习班，其目标是 土工试验场地或地震场地的选择 工程研究和一般岩土工程 research. 在建筑物的地基被挖掘之前， 通过形态学、地质学和 水文测验探索的过程， 表征或定义基质的小尺度性质. 建筑工地是岩土工程所特有的：在 规定了其他工程学科、材料特性 在设计期间，或在建造或制造之前，以及 然后进行控制以符合质量标准。 岩土工程研究人员往往需要良好的 进行实验的地点。定位和 描述这些站点非常耗时（而且通常 昂贵的证明一个单一的廉价实验），通常 这些地点仅用于单一实验。有必要 开发具有良好特征和仪器化的场地， 可作为国家资源增加研究 生产力和研究小组之间的合作。的 困难的是定位和决定通用 网站，并在规划的维护，管理，和长期 长期资助这些网站。本次研讨会的目的是 解决这些问题，特别是确定最佳网站， 确定建筑物的具体计划， 提供仪器，并编制成本估算， 每个网站的开发和运营。 试验地点将用于：（a）研究土壤现象 对动态载荷的响应，特别是液化，（B） 调查：（1）埋地管道的抗震能力 （2）已建设施的抗震能力; （3）土-结构相互作用现象（如 桩的性能），以及（c）评估新的工具， 测试、实验室测试和仪器仪表。的报告 国家研究理事会关于“液化的土壤在 地震”建议建立一个实验性的 试验场要探索。
