开采沉陷对高耸建筑物的影响研究
|
摘要
通过分析开采沉陷各种地表移动和变形对建筑物的影响机理以及高耸建筑物的特点,得出地表倾斜是造成高耸建筑物破坏的主要因素。依据高耸建筑物的地表允许和极限变形值,将高耸建筑物的破坏程度划分为轻度、中度和严重破坏三个级别。根据开采沉陷对高耸建筑物的最终影响结果,提出将开采沉陷对高耸建筑物的影响分为第一类影响和第二类影响。讨论了高耸建筑物的保护措施,提出可以借助数值模拟的方法分析高耸建筑物的破坏程度的思想。以概率积分法为预计模型,对112103工作面附近的一个烟囱进行了开采沉陷影响分析。
The main factor of destruction high buildings was drawn by analyze of the mechanisms of various surface movements and deformations due to mining subsidence on the affection of the buildings and the features of high buildings,it is the slope.According to surface allowable and ultimate value,high buildings destruction was divided into three ranks,i.e.,mild,moderate,serious.The mining subsidence affected to high buildings was divided into category 1 and category 2 affection,based on the final mining subsidence affected to high buildings.The measures to protect high buildings against mining subsidence were discussed,and a thought was put forwarded that high buildings destroy can be analyzed using simulate.An affection of mining subsidence was analyzed for a chimney which is near 112103 working face with probability integral method as the prediction model.
