摘　　要：条带采空区上方的残余变形给拟建建筑物的运营带来了安全隐患,在对其上方的土地建筑利用前非常有必要进行科学的地基稳定性评价,文中在全面考虑条带采空区地基稳定性影响因素的基础上,对各因素进行了详细的分析,筛选出5个一级指标和17个二级指标,建立了相应的评价指标体系,最终基于模糊数学理论对条带采空区地基稳定性评价方法进行了简要分析,为相关理论研究和工程实践提供借鉴和参考。Residual deformation above the strip goaf brought the potential safety hazards to the operation of the proposed building,it was very necessary to conduct the scientific foundation stability evaluation before the use of the land and buildings above the strip goaf.Based on the comprehensive consideration of the influencing factors of the foundation stability of the strip goaf,in this paper,each factor was analyzed in detail,and 5 first-class indicators and 17 second-class indicators were selected,and the corresponding evaluation index system was established.Finally,the evaluation method of the foundation stability in strip goaf was analyzed briefly based on the fuzzy mathematics theory,which provided the reference for the relevant theoretical research and the engineering practice.
