摘要
以相似材料模型为基础,对老采空区上方进行多次分级加压,采用XJTUDP系统进行观测处理,得到了不同荷载下地表的变形规律以及相同荷载作用下不同岩层的变形规律,并通过回归分析得出了老采空区在新增荷载作用下地表下沉的预计公式,能够为老采空区上方新建建筑物的评价和治理提供一定的依据。
Based on the experiment with similar material,the top of the goaf was loaded the pressure several times.The XJTUDP system was used to observe the process the model.The laws of the subsidence under different loads and the laws of deformation of rock with different depths were obtained.Through regression analysis,the formula for expected the subsidence under the pressure is proposed,which can provide the basis for evaluation and treatment measures of the new buildings over the goaf.
