| 摘 要： | 为了评估煤矸石回填区光伏建设场地地基稳定性，在分析煤矸石回填层变形特性的基础上，提出了弹性力学模型和开尔文模型相结合计算煤矸石回填层地表残余沉降变形的技术思路。研究结果表明，考虑回填时间和回填厚度因素的煤矸石回填层残余沉降变形计算方法简单实用，能够满足工程需要，计算结果可为光伏设备基础设施建设提供设计依据。

| Abstract: | In order to evaluate the foundation stability of photovoltaic construction site in coal gangue backfill area，based on the analysis of deformation characteristics of coal gangue backfill layer，the technical idea of combining elastic mechanics model and Kelvin model to calculate the surface residual settlement deformation of coal gangue backfill layer was proposed.The results showed that the calculation method of residual settlement deformation of coal gangue backfill layer considering the factors of backfill time and backfill thickness was simple and practical，which can meet the needs of the project.The calculation results can provide design basis for photovoltaic equipment infrastructure construction. |
