“…Understanding and accurately characterizing the physical properties of moraine soils are thus of great significance for the prediction and mitigation of these geohazards. The physical properties of moraine soils have been experimentally and numerically investigated, including their mechanical properties (Cherepanin et al., 2018; H. Hu et al., 2020; Lebourg et al., 2004; T. Liu et al., 2020; Renjifo & Makhnenko, 2021; Sharratt & Lindstrom, 2001; Stock et al., 2007), hydraulic conductivity (Demand et al., 2019; Ming et al., 2020; Pittman et al., 2019; Seyfried & Murdock, 1997; Watanabe et al., 2013), and thermal conductivity (Naylor et al., 2015; Tinsley & Pavía, 2019; X. Xie et al., 2018; Zhao et al., 2019).…”

A warming environment is promoting the thawing process in ice‐rich moraine soils in cold alpine regions, thereby accelerating the formation/development of geohazards in these regions. The mechanism of these geohazards is closely related to the thermal‐hydraulic (TH) coupling behavior of moraine soils, which has rarely been investigated. Here, we conducted a series of bench‐scale TH coupling simulations of moraine soils with ice inclusions in a warming environment. The numerical model was conceptualized from a field survey on the Qinghai‐Tibet Plateau, which consists of a porous medium embedded with multilayer ice cubes with warmer water continuously flowing through it. A TH coupling framework considering ice‐water phase change was established to implement this coupled simulation with different initial ice contents and hydraulic gradients. The simulated results showed phased and nonlinear evolutionary features of temperature, ice content, and permeability for the moraine soil system. Further analyses showed that these complex evolutionary features can be reproduced by empirical formulas, with concise expressions following dimensional consistency and some coefficients having potential physical meanings. The discriminant models of two equilibrium states were finally developed to predict the critical times of structure stabilization and thermal equilibrium of the moraine soil system. This study presents the complex evolution of TH coupling properties of moraine soils, and simultaneously demonstrates that these properties can be predicted and characterized.

The paper is devoted to the construction of road crossings on the territory of the Arctic shelf and the Extreme North (Far North), as well as on the Siberian and Far Eastern rivers in winter. That is going to contribute to reducing logistic costs from cargo shipping down the ice surface significantly. In this research, the authors examine ice-based composites, where thin-walled polyvinyl chloride pipes are placed in the middle of the sample cross-section as a reinforcer. Two types of pipes were tested: vent white and orange sewer (drain) ones. While doing several series of model experiments, the researchers find out that the load-bearing capacity of ice samples reinforced with these pipes show very much the same results. So it was decided to combine the averaged model experiments with these pipes into one concluding result. The mechanical characteristics of ice were figured out by crushing samples of ice prisms that are 60 cm long, with a cross-section size of 15x15 cm. The aim of the paper is to define the influence of thin-walled polyvinylchloride pipes on the plastic properties and load-bearing capacity of ice samples when they are being reinforced. The test results prove that when reinforced with a pipe, it is destructed more gradually, and the deformations before the destruction have greater values. However, the thin-walled SN2 and SN4 pipes add nothing to increasing load-bearing capacity, unlike the SN8 sample, which increased the load-bearing capacity by about 10%. Therefore, the reinforced mid-section of ice samples with thin-walled PVC pipes marginally increased the plasticity of the samples, without the marked increase in the load-bearing capacity.
