Abstract

This paper presents the results of a field pilot test about deformation of water supply pipelines due to freezing temperature. There is a difference between for frost heaving load to act on the water supply pipelines. If the Marston-Spangler theory is only considered for the frost heaving load to act on the water supply pipeline, it is likely to deviate from the safety of the water supply pipeline, strains of the water supply pipeline show a tendency of smaller value than the value of numerical analysis.

이 논문에서는 현장모형 실험을 통하여 동결온도에 따른 상수도관의 거동변형특성을 다루었다. 동결 온도 조건에 따라 상수도관에 미치는 동상압력과 Marston-Spangler 이론에 의한 동상 압력은 다소 차이를 나타내는 것을 보이며, Marston-Spangler이론만으로 관에 작용하는 하중을 고려하는 것은 안전측을 벗어날 수도 있다는 것을 염두 해야 한다. 또한 현장모형실험을 통한 상수도관의 변형률은 수치해석결과보다 작은 값을 나타내는 것을 확인하였다.
