Abstract: The pulsed nuclear magnetic resonance (P-NMR) method is commonly used to determine unfrozen water content in frozen soils. Traditionally, unfrozen water content is calculated using first return data from the free induction ...

Abstract: A large scale 105-m-long, 0.9-m-diam chilled pipeline experiment was conducted to assess the response of a production pipeline that transits between unfrozen (seasonally frozen) and permafrost soils in discontinuous ...

Abstract: We present a laboratory system designed for studying frost heave in fine-grained soil. The system consists of: a modified refrigerator, a frost heave test cell, a laser for measuring heave, a differential pressure transducer ...
