Workshop on National Test Sites for Earthquake Engineering and Geotechnical Engineering Research

这一行动是为了支持一个研讨会，其目标是选择一个或多个岩土工程试验场，用于地震工程研究和一般岩土工程研究。在建筑物的基础被挖掘之前，该遗址通过形态、地质和水文检查来确定其特征。在建筑工地探索表征或定义基底的小尺度特性的过程是岩土工程所独有的：在其他工程学科中，材料的特性是在设计期间，或在施工或制造之前指定的，然后进行控制以满足规范。岩土工程的研究人员经常需要在具有良好特征的地点进行实验。定位和描述这些地点是非常耗时的（而且常常花费太大而无法证明一个廉价的实验），通常这些地点只用于一个实验。有必要开发具有良好特征和仪器的地点，作为国家资源，以提高研究生产力和研究小组之间的合作。困难在于定位和决定一般用途的地点，以及对这些地点的维护、管理和长期资助进行规划。这次讲习班的目的是解决这些问题，特别是确定最佳场址，确定建造结构和提供仪器的具体计划，并为每个场址的发展和运作编制费用概算。这些试验场将用于：(a)研究土壤对动力荷载的反应现象，特别是液化；(b)研究：(1)地埋管道对地震震动的抵抗；（二）已建设施的抗震性能；(3)土-结构相互作用现象（如桩的性能），(c)评估现场测试、实验室测试和仪器仪表的新工具。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一个试验试验场。

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.
