Table 1 Summary of the research methods for assessing or estimating the interaction behaviours between a buried pipeline and frost heave/thaw.
Author(s) | Model situation | Limitations |
---|---|---|
Nixon, et al.16 | Soil: Elastic or nonlinear viscous continuum Boundary: Nonlinear boundary Pipeline: Completely passive component | The pipelines were regarded as completely passive components; The frost heave was separated from pipeline stress; The frost heave was treated as linear expansion |
Soil: Elastic, viscoplastic body Pipeline: Flexible Beam Frost heave: Water heat coupling Characteristic: Separate consideration | ||
Soil: Elastoplastic body Pipeline: Beam Unit Frost heave: coefficient of linear expansion | ||
Selvadurai and Shinde18 | Soil: Elastic foundation Pipeline: Beam element/solid element/shell element Frost heave manifestation: experience determines the geometric shape and development of frost bubble growth | The manifestation of frost heave does not align with empirical observations |
Kanie, et al.23 | Soil: Elastic foundation Pipeline: Beam Frost heave: Takashi empirical equation | |
Nixon24 | Frost heave: Separation ice model Focus: Two dimensional frost heave prediction | Mainly aimed at predicting frost heave |
Frost heave: Improvement of Takashi’s empirical equation Focus: Two dimensional and three-dimensional frost heave prediction | ||
Rajani and Morgenstern17 | Soil: Elastoplastic foundation Pipeline: Beam Focus: Anti pull behavior of shallow buried pipelines | Non frozen soil |
Liu28 | Soil: Elastic foundation Pipeline: Thin walled structure Focus: Mechanical behavior analysis of pipeline cross-section |
