An Investigation of Geotechnical Aspects of the January 17, 1994 Northridge Earthquake - Preliminary Assessment

这一行动是为了支持收集1994年1月17日北岭地震的岩土工程数据，以便更好地了解地震强烈地面震动的原因和影响。收集这些易腐烂的数据的总体目标是应用所获得的知识来帮助减轻未来地震的影响。对于这个项目，特别侧重于收集数据以评估以下方面：(1)液化（即地面破坏）和地面压实，以及相关的地面位移；(2)当地土壤条件对地面震动特征和破坏模式的影响；(3)天然斜坡的地震反应；(4)土质结构（如水坝、堤防、固体废物填埋场、机械稳定挡土结构和结构填方）的地震反应。＊＊＊

9414375 Sitar This action is to support the collection of geotechnical engineering data on the Northridge earthquake of January 17, 1994 , so as to better understand the cause and effects of earthquake strong ground shaking. The overall objective in gathering this perishable data is to apply the knowledge gained to help mitigate the effects of future earthquakes. For this project, particular focus is directed towards gathering data for assessing the following: (1) the liquefaction (that is, ground failure) and ground compaction, and the associated ground displacements, (2) the effect of local soil conditions on ground shaking characteristics and damage patterns, (3) the seismic response of natural slopes, and (4) the seismic response of earth structures such as dams, embankments, solid waste landfills, mechanically stabilized retaining structures, and structural fills. ***
