US-Egypt Cooperative Research: Seismic Hazard Mitigation and Soil Strength Mapping for Land Use Planning in Tushka Area, Upper Egypt

0104310 Versteeg描述：该项目支持哥伦比亚大学拉蒙多尔蒂地球观测站的Roelof Versteeg博士和埃及阿斯旺国家天文和地球物理研究所阿斯旺地震中心的Raafat Fat-Helbary博士之间的合作项目。 他们计划为Tushka项目创建一个可用的地震危险和土壤强度地图，Tushka项目是上埃及的一个大规模新基础设施项目。 PI计划将描述超过指定地面运动水平的频率的概率地震危险图与可以提供详细现场影响的表面波分析技术相结合。 他们将把联合收割机MASW类型的反演技术与成像相结合，以获得对工程项目有很大用处的剪切波速度剖面。 结果将在地理信息系统环境中提供。 这项工作将开发一种技术，可以有效地补充宏观尺度的危险分析，并使精细的危险的一个真实的可能性，在选址的关键facility.Scope：该项目具有重要的科学和实践意义。 上埃及地区的地理位置很重要，受到最近人类发展的影响，包括阿斯旺大坝的建设。 这项研究将记录和解释地球物理和岩土工程数据，并将寻求为未来的项目开发实用信息。 Versteeg博士在获取和处理地球物理数据以及将这些数据集成到基于GIS的产品中以供非地球物理学家使用方面具有所需的经验。 Fat-Helbary博士在Tushka地震研究方面经验丰富。 他将领导收集大规模数据集的工作，并将领导创建地面运动加速度地图的工作。 双方都将从这种合作中受益，并有机会从正在进行的开发世界上具有历史意义的地区的规划中学习。 本拟议项目中的经验和方法将适用于埃及以及世界其他地区今后的发展。 PI完全符合计划的要求。 该项目符合支持合作研究的INT标准。

0104310VersteegDescription: This project supports a collaborative project between Dr. Roelof Versteeg, Lamont Doherty Earth Observatory, Columbia University and Dr. Raafat Fat-Helbary, Aswan Seismological Center, the National Research Institute of Astronomy and Geophysics, Aswan, Egypt. They plan to create a useable seismic hazard and soil strength maps for the Tushka Project, a massive new infrastructure effort in Upper Egypt. The PIs plan on combining probabilistic seismic hazard maps that describe the frequency of exceeding specified ground motion levels with a surface wave analysis technique that can provide detailed site effects. They will combine MASW type of inversion techniques with imaging to obtain shear-wave velocity profiles that can be of great use for engineering projects. The results will be made available in a GIS environment. This work will develop a technique that can usefully complement macro-scale hazard analysis, and make refined microzonation of hazard a real possibility useful in siting of critical facilities.Scope: The project has important scientific and practical implications. The geography of the Upper Egypt area is important and has been affected by recent human development including the construction of the Aswan High Dam. This research will document and interpret geophysical and geotechnical data and will seek to develop practical information for future projects. Dr. Versteeg has the needed experience in the acquisition and processing of geophysical data as well as the integration of these data into GIS based product for use by non-geophysicists. Dr. Fat-Helbary is experienced in the Tushka seismic studies. He will lead the effort for collection of the large-scale data sets, and will lead the effort in creating ground motion acceleration maps. Both sides will benefit from this collaboration and from the opportunity to learn from the type of planning that is underway to develop a region of the world that has historical significance. The experience and methods developed in this proposed project will be applicable to future developments in Egypt as well as in other parts of the world. The PIs are well qualified for the planned. The project meets INT criteria for support of collaborative research.
