US-Egypt Cooperative Research: Development of a Multi-Function Geosynthetic Testing Apparatus.

0001571 Ashmawy描述：该奖项旨在支持佛罗里达坦帕市南佛罗里达大学土木与环境工程系Alaa Ashmawy博士和埃及开罗国家研究中心工程研究部Ahmed Hosny Abdel-Rahman博士的合作项目。 科学家们计划建立一个多功能的大型测试设备，对土工合成加筋土进行全面的实验室计划。 我们的目标是发展的能力，调查这些加筋土的性能影响因素，并开发更准确的模型，用于数值模拟加筋土结构。范围：美国PI和埃及合作者在该研究领域拥有丰富的经验。 埃及科学家已经开展了理论工作，为土工合成材料（如土工膜、土工织物和土工格栅）加固的土壤开发模型。 这位美国科学家正在佛罗里达交通部的资助下调查土工合成材料的长期行为。本研究的目的是解决实施的土工合成板作为地球加强夹杂物的土体。 这种材料的使用在美国的土木和环境项目中越来越受欢迎，在埃及也开始受到重视，因为它是一种有效的手段，可以在建造建筑物和挡土墙时、在流体过滤和排水以及在垃圾填埋场等废物控制中增加土壤强度。 USF的一名美国研究生将参与这项合作。 该提案符合INT的目标，即支持在共同感兴趣的领域进行合作研究。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。

0001571AshmawyDescription: This award is to support a collaborative project by Dr. Alaa Ashmawy, Department of Civil and Environmental Engineering, University of South Florida, Tampa, Florida, and Dr. Ahmed Hosny Abdel-Rahman, Engineering Research division, the National Research Center, Cairo, Egypt. The scientists plan to build a multi-function large-scale testing apparatus to conduct a comprehensive laboratory program on geosynthetically reinforced soils. The goal is to develop the capability to investigate the factors affecting the performance of these reinforced soils and to develop more accurate models for use in numerical simulation of reinforced earth structures. Scope: The US PI and the Egyptian collaborator have extensive experience in this area of research. Theoretical work has been carried out by the Egyptian scientist to develop models for soils reinforced with geosynthetic materials, such as geomembranes, geotextiles and geogrids. The US scientist is investigating the long-term behavior of geosynthetics under funding from the Florida Department of Transportation. The present research is intended to address the implementation of the geosynthetic sheets as earth-reinforcing inclusions to soil masses. The use of such materials is gaining popularity in civil and environmental projects in the United States and is beginning to gain attention in Egypt as an effective means to increase soil strength when building embankments and retaining walls, in fluid filtration and drainage and in waste containment such as in landfills. One US graduate student at USF will participate in this collaboration. This proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
