포화 사질토 뒷채움재의 비배수 동결에 의한 매설 강관의 거동 – 실대형 모형실험 연구 - = Effects of Freezing a Backfill Material under Undrained Condition on a Buried Pipe

다국어 초록 (Multilingual Abstract)

Frost heaving and thawing settlement cause unexpected stress around buried pipelines, which results in deformation and permanent demage. A large scale laboratory test has been performed to observe deformation, stress, and temperature of a buried pipe during atmospheric temperature changes. From the experimental results, the stress concentrated around the buried pipe is inevitable and deformation is caused by the frost heaving. Even though backfill materials are sandy soils which are normally assumed to be non frost susceptible, it is revealed that frost demage can happen due to drainage condition, the level of ground water table, and water content.
