Abstract

The primary factors causing road damage in high-latitude areas are frost heave and thaw settlement, which are governed by hydrothermal changes. An indoor freeze-thaw cycle test based on similarity theory was conducted to analyze the hydrothermal evolution of high-latitude frozen soil in Northeast China. The results were verified by field data. A hydro-thermal coupling Eq. was established by using finite element software. The experimental and simulation results were compared to validate the finite element model of the soil column. The freeze-thaw cycles exhibited three distinct phases: freezing initiation, peak freezing intensity, and thawing. The soil moisture at the end of each freeze-thaw cycle increased, decreased, and increased. The proposed hydrothermal coupling model was used to describe the long-term freeze-thaw behavior of typical subgrade sections in high-latitude permafrost regions of China. The model based on similar particle gradation proved accurate.

高纬度冻土在冻融循环中的热液演化

高纬度地区道路破坏的主要原因是冻胀和融化沉降，而冻胀和融化沉降受热液变化的支配。基于相似理论的室内冻融循环试验，分析了东北高纬度冻土热液演化过程。实测数据验证了结果的正确性。利用有限元软件建立了水热耦合方程。将试验结果与仿真结果进行对比，验证了土柱有限元模型的正确性。冻融循环表现为冻结起始阶段、冻结峰值阶段和解冻阶段。在每个冻融循环结束时，土壤水分依次增加、减少和增加。利用所建立的水热耦合模型对中国高纬多年冻土区典型路基段的长期冻融行为进行了描述。基于相似颗粒级配的模型被证明是准确的。

期刊介绍： Advances in Water Resources provides a forum for the presentation of fundamental scientific advances in the understanding of water resources systems. The scope of Advances in Water Resources includes any combination of theoretical, computational, and experimental approaches used to advance fundamental understanding of surface or subsurface water resources systems or the interaction of these systems with the atmosphere, geosphere, biosphere, and human societies. Manuscripts involving case studies that do not attempt to reach broader conclusions, research on engineering design, applied hydraulics, or water quality and treatment, as well as applications of existing knowledge that do not advance fundamental understanding of hydrological processes, are not appropriate for Advances in Water Resources. Examples of appropriate topical areas that will be considered include the following: • Surface and subsurface hydrology • Hydrometeorology • Environmental fluid dynamics • Ecohydrology and ecohydrodynamics • Multiphase transport phenomena in porous media • Fluid flow and species transport and reaction processes
