Modeling the Viscoelastiodynamic Response of the Wasatch Mountains, Salt Lake Basin and Mountaindale Dam, Utah

本次研究是通过重力和地震活动来确定 折射波法研究盐湖的地下结构 谷，犹他州，模型的三维有限元结构 规范的地震波反应，并将结果与 记录地震数据。 这项研究预计将 提供了一个新的理解竞争之间的相互作用 衰减效应，地形散射，盆地共振， 盆地边界的体-面波转换和尾波 增强 地形散射结果将被应用于 前往犹他州瓦萨奇山脉的大坝， 传统的地震反应设计标准是足够的。 这项研究是国家地震灾害的一个组成部分 减少方案。

This research is to define by gravity and active seismic refraction methods the subsurface structure of the Salt Lake Valley, Utah, model the resulting structure in a 3-D finite element code for response to earthquake waves, and compare the result with recorded data from earthquakes. The research is expected to provide a new understanding of the competing interactions among the effects of attenuation, topographic scattering, basin resonance, body-to-surface wave conversion at basin boundaries, and coda enhancement. The topographic scattering results will be applied to dam sites in the Wasatch Range, Utah, to determine if conventional earthquake response design criteria are adequate. This research is a component of the National Earthquake Hazard Reduction Program.
