摘要
针对开采引起地层下沉非线性变形的特点，用可变形离散单元法模拟了离层注浆减缓地层下沉过程。探讨了离散元分析中参数选取的办法，模拟结果表明，可变形离散元法分析地层非线性变形是可行的。
To counter the character of nonlinear deformation of stratum subsidence due to excavation, the decrement of stratum subsidence is imitated with leaving layer grouting by using deformable discrete element method. The selection is studied of discrete element parameters and the imitation result shows that the deformatble discrete element method can be used to analyse the nonlinear deformation of stratum.
