“…Studies on the mechanical behavior of buried pipelines under low temperature have been conducted using numerical simulations [20][21][22][23][24][25][26][27], experimental methods [22,[28][29][30][31] and analytical methods [23,32,33]. Wu et al [23] investigated the mechanical behavior of underground oil pipeline in permafrost region using an elastic-plastic finite element model, considering the effects of temperature and moisture fields.…”

Water distribution pipelines play a critical role in delivering safe drinking water to communities, yet their susceptibility to extreme climate events presents significant safety and structural challenges. Recent observations have noted an increase in pipe failures during cold waves, underscoring the need to address these risks. While much research has focused on statistical analysis of pipe failures due to low temperatures, limited attention has been given to the mechanical behavior of pipelines under thermal-induced stress during cold waves. This study addresses this gap by developing a 3D finite element model to investigate the thermal responses and mechanical behavior of buried water distribution pipelines under cold wave conditions. Key parameters including temperature differences, soil temperature reduction rates, pipe wall thickness, and internal water pressure are examined to understand their effects on pipeline stress, strain, and displacement. Results show that as pipe temperature decreases, the pipe contracts, particularly impacting the springline. Over time, pipeline stress transitions from tension to compression. A temperature difference of approximately 18℃ leads to an 85% increase in axial strain and a 6.5% increase in Mises stress. Increasing the rate of temperature reduction minimally affects pipeline stress but significantly impacts displacements. Moreover, increasing pipe wall thickness effectively reduces pipeline stress by 102.8% and axial strain by 17.4%. Higher internal water pressure results in elevated pipeline stress but reduced displacement. These findings underscore the importance of considering thermal-mechanical interactions during cold waves to prevent failures and ensure operational integrity in water distribution pipelines.

“…In [15], the thermal processes in the saturated porous medium around the GHE were simulated using FEFLOW 2D axisymmetric model with C++ plug-in for phase changes between solid and liquid phases. Possible ways to avoid GHE pipes deformation and reduce flow resistance under freezing conditions were studied via experimental tests in [16] and using numerical simulation in [17].…”

“…Physical modeling can also be used to describe the complex hydro-thermodynamic interaction that occurs when a thermal probe exchanges energy with the surrounding environment. For example, Wang et al (2013) built a 900 × 800 mm experimental setup in order to investigate the interactions between soil and pipes in case of ground freezing phenomena: they analyzed the effects of soils with different grain sizes on the movement of the freezing front and on the deformations induced on the pipes. Cimmino et Bernier (2015) built an experimental setup constituted of a small-scale 400mm-long borehole inserted into a 2 m 3 sand tank with known thermal properties in order to obtain the experimental g-function, starting from measurements of the borehole wall temperature and of the net heat injection.…”

The design of a Borehole Heat Exchanger (BHE) is based on the evaluation of the thermal exchange capacity of the whole system constituted by the probes and the surrounding ground. The energy performance of a BHE mainly depends on the thermal properties of the sediments, the possible groundwater flow and the changes in the thermal gradient in the probe's surroundings due to the continuous heat exchange with the subsoil. The interpretation of the in-field applications is often difficult because in many instances the information needed is unavailable due to difficulties of in-field
