| 中文摘要: |
| 以焦作煤业集团小马矿老采空区为例,利用现场调研与理论分析相结合的方法,对老采空区的活化影响因素进行了分析,造成老采空区“活化”的因素主要是2个:一是老采空区垮裂带发生“活化”,二是载荷下的地表移动与变形,利用数值模拟对房屋载荷引起的地表移动变形对地基稳定性的影响进行了研究,得出了研究区内3个不同区域的地基最大载荷能力,进而对相应区域内的楼层建设高度提出建议,最后给出了老采空区的地基处理措施,从而整体对老采空区的建筑适宜性进行了分析,对实际建设工程提供参考. |
| 英文摘要: |
| Taking the old goaf of Xiaoma Mine, Jiaozuo Coal Group Corporation as an example, this paper combines on-site research with theoretical analysis to analyze the activation factors of the old goaf. There are two factors that cause the activation of the old goaf. One is that the old goaf collapse torn belt produces activation, the other is the surface movement and deformation under load. This paper uses the numerical simulation to study the ground movement caused by the housing load deformation of foundation stability, and obtain three foundation maximum load capacities in different areas. Then, it gives some proposals about the corresponding area height of the floor construction. Finally, it analyzes the foundation treatment measures goaf, and the overall suitability for building goaf, providing references for the actual construction projects. |
