U.S. Germany Cooperative Research: Prediction and Interpretation of Soil-Structure Interaction for Deep Excavations

该奖项支持安德鲁·惠特尔和麻省理工学院的学生与德国柏林工业大学土木工程系的斯塔夫罗斯·萨维迪斯合作。研究的重点是预测开挖引起的地表移动的新分析方法。麻省理工学院的团队在分析波士顿地区现有的粘土类型方面拥有丰富的经验，而德国团队拥有对柏林附近常见的沙质土壤进行建模的专业知识。总之，这两个小组将有独特的机会比较不同土壤类型的本构模型和实验室表征方面的发展，以改进和改进现有的模型。这项研究的结果将有助于改进工具，以减轻在大型建筑和交通项目开挖阶段对邻近结构和公用事业造成的破坏。这一联合合作研究工作也为初级研究人员提供了在国际上工作的机会，就这一提议所做的工作将有助于使德国和美国研究小组之间的关系制度化。

0089508WhittleThis award supports Andrew Whittle and students from the Massachusetts Institute of Technology in a collaboration with Stavros Savidis of the Department of Civil Engineering at the Technical University of Berlin, Germany. The research focus is on new methods of analysis for predicting ground movements caused by excavations. The MIT group has extensive experience in analyzing clay soils of the type present in the Boston area, whereas the German group has expertise modeling sandy soils common in the vicinity of Berlin. Together, the two groups will have the unique opportunity of comparing developments in constitutive modeling and laboratory characterization of different soil types in order to refine and enhance current models. The results of this research will lead to improved tools for mitigating damage to adjacent structures and utilities caused during excavation phases of large building and transportation projects. This joint collaborative research effort also presents junior researchers with the opportunity to work internationally, and the work done on this proposal will help institutionalize the relationship between the German and U.S. research groups.
