US-Norway Cooperative Research: Soil Sample Disturbance Assessment

0305526 Sheahan该奖项与挪威奥斯陆挪威岩土研究所近海岩土工程部的Tom Lumne合作，为来自西北大学的PI和研究生提供支持。这项合作将在如何对软土采样、测量样本扰动程度以及评估扰动对测量行为的影响方面推进最先进的技术。该研究计划还将使美国在这一领域的抽样实践从过去50年来基本保持不变的状态，转变为目前能力的前沿。岩土工程设计和研究中的很大一部分不确定性来自于样品的扰动，而目前的取样和试验方法会引起大范围的样品扰动，从而影响材料的性能。美国和挪威的合作使美国集团能够接触到世界上一流的岩土研究机构，只会增加国内研究的成功。该项目还实现了一个培训目标。这个国际项目将允许参与的研究生从在另一个国家进行研究中受益。他们将培养对周围世界的高度欣赏，同时也学习重要的新技术技能。

0305526SheahanThis award supports the PI and graduate students from the Northwestern University in a collaboration with Tom Lunne of the Offshore Geotechnical Engineering Division of the Norwegian Geotechnical Institute in Oslo, Norway. The collaboration will advance the state of the art in how soft soils are sampled, the degree of sample disturbance is measured, and effects of disturbance on measured behavior are evaluated. The research program will also bring the state of US sampling practice in this area from one that has remained essentially constant for the past 50 years to one that is at the forefront of present capabilities. A great part of the uncertainty in geotechnical design and research comes from sample disturbance and current methods of sampling and testing cause a wide range of sample disturbance that affects material behavior. The US-Norway collaboration gives the US group access to the premier geotechnical research institute in the world, and can only add to the success of the domestic research.The project also fulfills a training objective. The international project will allow graduate students involved to benefit from performing research in another country. They will develop a heightened appreciation of the world around them while also learning important new technical skills.
