Experiments on structural models and full-scale structures are important to understanding the behavior of structures subjected to earthquake loadings. Techniques such as shake table experimentation, pseudo-dynamic experimentation, and static experimentation have been used in the past for various applications with some degree of success. This research project will examine the controlled underground expansion technique for use as a facility for inducing earthquake-type ground motion into model structures. Emphasis will be placed on achieving ground displacements up to 10 inches. The results of this research are directly applicable to the design of an in situ experimentation facility for use in structural dynamics research.

结构模型试验和足尺结构试验 重要的是要了解结构的行为受到 地震荷载 例如振动台实验， 拟动力实验和静态实验， 在过去用于各种应用并取得了一定程度的成功。 这项研究项目将检查控制地下扩张 用作诱发地震型地面设施的技术 运动到模型结构中。 重点将放在实现 地面位移可达10英寸 这项研究的结果是 直接适用于现场试验设计 用于结构动力学研究的设备。
