摘　　要：以某水利枢纽多年冻土为例,在工程地质勘察的基础上,结合冻土土工试验和地温观测数据,分析工程区多年冻土的分布范围和特征、冻胀性、融沉性、热学性质等主要的工程地质问题,并提出了相应的地基基础设计方案。In this paper, taking a hydro project in permafrost area as an example, based on the engineering geological investigation, the frozen soil tests and the ground temperature observation data, the distribution and the characteristics of the existing permafrost are studied. The frost heaving, the thawing settlement and thermal property of the permafrost are analyzed. Then, the main engineering geological problems of the study area are pointed out, and corresponding foundation design scheme are proposed.
