摘要
分析了覆岩离层注浆控制层 (岩梁 )的受力过程 ,提出了注浆减缓地表沉陷的受力模型 ,从中得出了注浆减沉的力学机理 ,进一步得到了注浆减沉的动态力学模型 。
The stress and strain of control layers (beams) is analyzed. The mechanism of reducing subsidence by filling ash liquid into strata is obtained. And further, dynamic mechanics models are achieved. The measurements to improve the result of reducing subsidence is put forward.
