摘要
提出了采煤沉陷区地基空间稳定性和时间稳定性的概念及采煤沉陷区地基稳定性分析的4个要点,详细分析了地基主要受力层与老采空区裂缝带的空间关系、采煤沉陷稳定时间、采煤沉陷区残余残余移动变形的计算及其对地基稳定性的影响。以北票矿区采煤沉陷区治理工程为例,说明了采煤沉陷区地基稳定性分析在指导采煤沉陷区治理规划方面的应用。
The paper pointed out the conceptions of the space stability and the time stability for the foundation in the coal mining subsid- ence area and the four main points for the analysis on the foundation stability in the coal mining subsidence area. The paper analyzed the space relationship between the main loaded layer of the foundation and the cracking zone of the goaf, the time for mining subsidence stabilization, the calculation for the rest displacement deformation in the mining subsidence area and the influence tO the foundation stability. Taking the foundation treatment and control project in the mining subsidence area Of Beipiao Mining area as an example, the paper showed that the stability analysis Of the foundation in the mining subsidence area applied to the treatment and control planning of the mining subsidence area.
