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.

此行动是为了支持一个研讨会，其目标是选择地震工程研究和一般岩土工程研究的岩土工程测试地点或地震。 在挖掘建筑物的基础之前，该地点的特征是形态，地质和水文检查的手段。探索以表征或定义建筑工地基质的小规模特性的过程是岩土工程的独有的：在其他工程学科中，在设计期间或在施工或制造之前指定材料特性，然后进行控制以满足规范。 岩土工程学的研究人员通常需要进行实验的表征良好的地点。定位和表征这些站点非常耗时（通常太昂贵，无法证明一个廉价的实验是合理的），通常这些站点仅用于单个实验。有必要开发出良好的特征和仪器地点，这些地点可作为国家资源，以提高研究小组之间的研究生产力和合作。困难在于定位和决定通用站点，并计划对此类站点的维护，管理和长期资助。本研讨会的目的是解决这些问题，特别是为了确定最佳地点，定义了结构建设和提供仪器的特定计划，并为每个站点的开发和运营准备成本估算。 将使用测试地点：（a）研究土壤对动态负荷的反应现象，尤其是液化，（b）研究：（1）埋入管道对地震摇动的耐药性； （2）建筑设施的地震抵抗； （3）土壤结构相互作用现象（例如桩的性能），以及（c）评估现场测试，实验室测试和仪器的新工具。国家研究委员会关于“地震期间土壤液化”的报告建议探索建立实验测试地点。
