摘要9900145 PI: S. L. Gassman和C. E. Pierce，哥伦比亚南卡罗来纳大学标题：“获取用于教育和研究的自动三轴测试系统”该设备拨款为南卡罗来纳大学土木与环境工程系岩土工程实验室获取自动三轴测试系统提供资金。期望的系统能够在排水和不排水条件下进行控制应力或应变加载速率和不同类型的规定应力路径的测试。获得这种专业实验室设备的主要目的是提高南卡罗来纳大学岩土工程研究和教育活动的质量和范围。特别地，这个三轴系统将被用来促进两位初级教员的高级研究，并通过在几门课程中直接使用它来提高本科和研究生课程。这个三轴系统将直接影响到目前资助的受控低强度材料研究项目的未来方向和支持，以及在本署维护的岩土工程测试坑中进行的几项正在进行的研究。执行先进三轴试验的能力将使教师有竞争力获得其他研究项目，例如关于南卡罗来纳州土壤液化敏感性和现场仪器回填的应力-应变响应的拟议项目。该系统还将为土力学本科学生和岩土工程高级领域与实验室仪器新课程的研究生提供实验室体验。三轴试验可以让学生了解固结、围压水平和排水条件对抗剪强度的影响，从而增强他们对土力学的理解。通过向本科生和研究生展示正在进行的研究项目，将研究和教育结合起来。

Abstract 9900145 PI: S. L. Gassman and C. E. Pierce University of South Carolina, Columbia Title: "Acquisition of an Automated Triaxial Testing System for Education and Research" This equipment grant provides funds for the acquisition of an automated triaxial testing system for the geotechnical laboratory in the Department of Civil and Environmental Engineering at the University of South Carolina. The desired system is capable of performing tests of controlled rate of stress or strain loading and different types of prescribed stress paths under both drained and undrained conditions. The primary objective for obtaining this specialized laboratory equipment is to improve the quality and broaden the scope of geotechnical engineering research and educational activities at the University of South Carolina. In particular, this triaxial system will be used to facilitate advanced research by two junior faculty members, and enhance the undergraduate and graduate curriculum by its direct use in several courses. This triaxial system will directly impact the future direction and support of a currently funded research project in controlled low strength materials and several on-going studies in a geotechnical testing pit maintained in the department. The ability to perform advanced triaxial tests will make the faculty competitive to obtain other research projects, such as proposed projects on liquefaction susceptibility of South Carolina soils and stress-strain response of backfill for field instrumentation. This system will also provide laboratory experience for undergraduate students in Soil Mechanics and graduate students in a new course in Advanced Field and Laboratory Instrumentation for Geotechnics proposed by the junior faculty. Triaxial testing allows students to learn the effects of consolidation, confining stress levels, and drainage conditions on shear strength, and as such will enhance their understanding of soil mechanics. Research and education will be integrated by providing demonstrations of on-going research projects to both undergraduate and graduate students.
