This is a two-year collaborative research project between Dr. Ching S. Chang, University of Massachusetts and Professor Yuan Jian-Xin, Institute of Rock and Soil Mechanics, Chinese Academy of Science. This proposal plans to study mechanical behavior of loess and is jointly sponsored by NSF and Chinese Academy of Sciences. China has some of the world's largest and best known loess deposits. The Institute of Rock and Soil Mechanics (IRSM), the Chinese Academy of Science, at Wuhan, China has been actively researching the mechanical properties of these soils. It has a large quantity of experimental and field data. Dr. Chang has developed models that can account for many structural features in loess. The data available from the Chinese collaborative institute can validate and improve his models. Both the U.S. and China collaborators can greatly benefit from this collaboration and jointly they can enhance the understanding of the mechanical behavior of such soil.

这是美国马萨诸塞大学张庆生博士与中国科学院岩土力学研究所袁建新教授为期两年的合作研究项目。本课题由美国国家科学基金会（NSF）和中国科学院（Chinese Academy of Sciences）共同资助，拟对黄土的力学行为进行研究。中国拥有一些世界上最大、最著名的黄土矿床。中国科学院武汉岩土力学研究所（IRSM）一直在积极研究这些土壤的力学特性。它有大量的实验和现场数据。张博士开发的模型可以解释黄土的许多结构特征。中国合作研究所提供的数据可以验证和改进他的模型。美国和中国的合作者都可以从这种合作中受益匪浅，他们可以共同加强对这种土壤力学行为的理解。
