ABSTRACT: CMS-9714858, C.B. Crouse, Dames & Moore The strong ground shaking recorded at the Jensen Filtration Plant during the 1994 Northridge earthquake sequence (mainshock and aftershocks) offers a unique opportunity to study soil nonlinearity. Two accelerographs stations close together at the Jensen Filtration Plant in California recorded the earthquake motions; one station was situated over moderately stiff soil, the other on very stiff soil. The character of the two recordings -- which were quite different -- suggests that nonlinear soil response could have been significant at the moderately stiff soil site during the mainshock. However the two buildings containing station accelerographs at this site were also different, which raises the concern whether soil- structure interaction affected the motions at one or both stations. Thus the objective of this study is to investigate the influence of soil-structure interaction on the recordings. Two Federal agencies are collaborating in the support of this project: the US Geological Survey and the National Science Foundation.

摘要：CMS-9714858，C.B.摩尔夫人克劳斯 在1994年北岭地震序列（主震和余震）期间，詹森过滤厂记录的强烈地面震动为研究土壤非线性提供了一个独特的机会。 位于加州的詹森过滤厂的两个加速度计站记录了地震运动;一个站位于中等硬度的土壤上，另一个站位于非常坚硬的土壤上。这两个记录的特点-这是完全不同的-表明，非线性土壤反应可能是显着的，在中等硬度的土壤网站在主震。然而，在该场地的两座包含台站加速度计的建筑物也是不同的，这引起了人们的关注，即土壤-结构相互作用是否影响了一个或两个台站的运动。因此，本研究的目的是调查土-结构相互作用对记录的影响。 两个联邦机构正在合作支持这个项目：美国地质调查局和国家科学基金会。
