Detection of Pipeline Deformation Induced by Frost Heave Using OFDR Technology
Frontiers in Physics, 2021 Oil and gas pipelines are critical structures. For pipelines in the seasonal frozen soil area, frost heave of the ground will result in deformation of the pipeline. If the deformation continually increases, it will seriously threaten the pipeline safety.

Basic Study on the Frost Heave Pressure of Rocks : Dependence of the Maximum Frost Heave Pressure on Temperature [PDF]
, 2011 In this study, we attempted to measure frost heave pressure, i.e., the pressure that develops in the heat-flow direction when rocks are subject to frost heave and ice lenses grow.

Frost heave prediction of chilled pipelines buried in unfrozen soils
, 1984 Frost heave is an important consideration in the design of buried chilled pipelines. A procedure for calculating the amount of heave under a chilled gas pipeline is presented based on a finite-difference formulation of the heat and mass transfer in ...

Journal of Rock Mechanics and Geotechnical Engineering, 2023 The calculation of frost heaving with ice lens formation is still not standard for construction projects using artificial ground freezing (AGF). In fine-grained material, ice lenses may initiate and lead to significant heaving at the ground surface ...

Experimental and Modeling of Residual Deformation of Soil–Rock Mixture under Freeze–Thaw Cycles
Applied Sciences, 2022 Projects in seasonal frozen soil areas are often faced with frost heaving and thawing subsidence failure, and the foundation fill of most projects is a mixture of soil and rock. Therefore, taking soil–rock mixture with different rock contents as research

Research on Hydraulic Soil Slope Frost Heaving Damage Model Test
Applied Mechanics and Materials, 2012 Frost heaving damage of water conservancy project is widespread. In order to research the failure problems of hydraulic soil slope in dark seasonal frozen soil region, laboratory model test is carried out combined with field test section practical situation, which is the prototype of this model test.
