Engineering Research Equipment Grant: Full-Scale Facility for the Experimental Investigation of Attenuation Characteristics of Soils

此操作与 工程研究设备赠款 程序. 为以下项目提供资金： 购买特定设备;这些 用于井间地震 法 目标是在现场测量 土壤的阻尼特性。 对强度、刚度和 土壤的阻尼特性是 地震减灾 许多 已经开发出测量 强度和刚度特性，但 现场阻尼性能的测量 被证明非常困难。 交叉孔洞 地震方法在这方面显示出很大的潜力 请注意。

This action is associated with the Engineering Research Equipment Grants program. Funding is provided for the purchase of specific equipment items; these are for use in the cross hole seismic technique. The goal is to measure in situ the damping characteristics of soils. A knowledge of the strength, stiffness and damping properties of soils is fundamental to earthquake hazard mitigation. Many techniques have been developed to measure strength and stiffness properties, but the measurement of damping properties in situ has proven very difficult. The cross hole seismic method shows a lot of promise in this regard.
