| 摘 要： | 应用矿山灾害力学及结构力学等相关理论,针对我国各矿区正转入深部开采的现实情况,对矿区城市中的楼体地基建设的稳定性进行了数值模拟研究,得到了不同采深、不同高度楼房建设条件下地基及地下岩体的应力、变形及沉降规律,并借助相似材料模拟实验进行验证。结果表明:深部开采条件下,矿区城市地基所受应力主要体现在底部连接处,地基中部发生的变形和沉降较大。开采深度越大地基所受影响反而较小,楼层越高地基变形越大。通过相似材料模拟实验分析实际采区开采后的地表变化,发现开采深度较浅情况下地表破坏明显严重,而深部开采时地表所受破坏情况较小,但当地表承重加强时会发生破坏。模拟和实验为矿区城市在深部开采条件下的地基建设提供参考。

| Abstract: | By applying the theory of mine disaster mechanics and structural mechanics,and aimed at practical situation that the Chinese mines are getting into the deep mining,the numerical simulation on stability analysis of foundation in the mining towns leads to some helpful results.The stress,deformation and subsidence laws of foundation and underground rock with different mining depths and structural height are found.And the results are verified by similar material simulation experiments.The results show the stres... |
