摘要: 季节冻土地区土体频繁受冻融作用。利用相变材料吸放潜热特性对冻融土体进行改良，研究其对土体温度场的调整作用。对掺入微胶囊相变材料的粉砂土进行一维土柱冻融试验，分析掺入相变材料后，土体的相变特征和温度场分布。使用有限元软件ANSYS，建立掺入相变材料粉砂土温度场数值模型，对土柱的温度变化情况和分布规律进行深入对比和分析。研究为相变材料在季节冻土地区的应用提供科学依据和参考。
Abstract: The soil in seasonal frozen soil region is frequently subjected to freeze-thaw. The latent heat absorption and release characteristics of phase change materials are used to improve freeze-thaw soil, and the adjustment effect of phase change materials on soil temperature field is studied. One-dimensional soil column freeze-thaw tests were carried out on silty sand mixed with microencapsulated phase change materials, and the phase change characteristics and temperature field distribution of soil mixed with phase change materials were analyzed. Using the finite element software ANSYS, a numerical model of the temperature field of silty sand mixed with phase change material is established, and the temperature change and distribution law of the soil column are compared and analyzed in depth. The research provides scientific basis and reference for the application of phase change materials in seasonal frozen soil areas.
