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

VersteegDescription：该项目支持哥伦比亚大学Lamont Doherty地球天文台的Roelof Versteig博士和埃及Aswan国家天文与地球物理研究所Aswan地震中心的Raafat Fat-Helbary博士之间的合作项目。他们计划为图什卡项目制作可用的地震危险性和土壤强度地图，图什卡项目是上埃及的一个大规模新基础设施项目。PIS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提供详细场地影响的面波分析技术相结合。他们将把MASW类型的反演技术与成像相结合，以获得可用于工程项目的横波速度剖面。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规模的危险分析，并使精细的危险微区划成为一种真正的可能性，有助于关键设施的选址。范围：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，并受到最近人类发展的影响，包括建造阿斯旺高坝。这项研究将记录和解释地球物理和岩土数据，并将设法为今后的项目提供实用信息。Versteig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地理信息系统的产品中供非地球物理学家使用方面拥有所需的经验。Fat-Helbary博士在图什卡地震研究方面经验丰富。他将领导大规模数据集的收集工作，并将领导创建地震动加速度图的工作。双方都将从这一合作中受益，并有机会学习正在进行的规划类型，以开发一个具有历史意义的世界区域。在这一拟议项目中发展的经验和方法将适用于埃及以及世界其他地区的未来发展。PI非常适合于计划中的项目。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.
