Equipment for UCSD Geotechnical Centrifuge Laboratory

该合同部分支持为加州大学圣地亚哥分校(UCSD)土工离心机采购基本仪器和其他基本设备。为了适应这台离心机的研究和教学能力，加州大学圣地亚哥分校的地质力学实验室正在进行翻新。在拟议的工作完成后，离心机将能够进行用于教育和研究目的的仪器实验。教育应用程序将受到主要关注，其目的是通过互联网实现深远的可访问性。加州大学圣迭戈分校的本科生和研究生已经参与了这一发展阶段(http://webshaker.ucsd.edu)。近期的研究目标包括使用电动马达致动器系统在浅基础和深基础上进行地面循环加载试验。该系统将成为广泛的土-结构相互作用领域中基于抗震性能的设计研究的支柱。其他长期计划包括开发机器人能力，以扩大教育和研究应用的多样性。这种机器人应用包括钻孔灌注桩(CIDH)施工的飞行模拟以及其他地基/基础修改/翻新技术

This award partially supports the acquisition of a basic instrumentation package and other essential equipment for the University of California San Diego (UCSD) geotechnical centrifuge. In order to accommodate the research and educational capabilities of this centrifuge, the Geomechanics Laboratory at UCSD is being renovated. Upon completion of the proposed work, the centrifuge will be capable of conducting instrumented experiments for both educational and research purposes. Educational applications will receive major attention with intended far-reaching accessibility via the Internet. Undergraduate and graduate UCSD students are already participating in this development phase (http://webshaker.ucsd.edu ). Near-term research objectives include use of an electric-motor actuator system to conduct above-ground cyclic loading tests on shallow and deep foundations. This system will be the backbone of seismic performance-based design research in the broad area of soil-structure interaction. Additional long-term plans include the development of robotics capabilities in order to broaden the variety of educational and research applications. Such robotics applications include in-flight simulation of Cast-In-Drilled-Hole (CIDH) pile construction, as well as other ground/foundation modification/retrofitting techniques
