摘　　要：为了解大规模跨季节土壤储热系统的研究进展,从设计参数、物理模型、数学模型、系统运行及优化和应用场景等方面对比分析跨季节土壤储热体发展现状。分析发现,现有研究对钻井间距、土壤热导率等关键设计参数之间的成比例关系研究较少,如钻井间距与钻井直径之比、钻井体积与埋管体积之比,后续工作可沿该思路展开。此外,研究认为从无需补充电力、燃煤、燃气等额外能源即可实现供热调峰的角度分析,利用跨季节土壤储热技术承担调峰任务要比调峰锅炉更具优势。In order to understand the research progress of large-scale seasonal soil heat storage system,this paper compares and analyzes the development status of seasonal soil heat storage system from the aspects of design parameters,physical model,mathematical model,system operation and optimization,and application scenarios.After analysis,it is found that there are few studies on the proportional relationship between key design parameters such as drilling spacing and soil thermal conductivity,such as the ratio of borehole spacing to borehole diameter and the ratio of borehole volume to buried pipe volume.Subsequent work can be carried out along this idea.From perspective of the need for additional energy sources such as electricity,coal and gas to achieve heat supply peak regulation,it is suggested that seasonal soil heat storage technology should be used to replace the peak heating function of the heating peak shaving boiler.
