The mathematical models based on fuzzy mathematics and grey system theory were applied to the prediction of the natural slope failure due to underground excavation under complex topography in mountain areas.
针对复杂地形条件下工程开挖的实际情况，利用Ｆｕｚｚｙ数学和灰色系统理论建立了预测山区地下开挖引起岩体及自然边坡失稳的数学模型，并对具体矿山工程中岩体移动和自然边坡失稳问题进行了计算和分析。
Large displacements of slope and surface deformation due to underground excavation are discussed using the DDA model with results compared with those from DEM.
基于 DDA计算模型 ,补充和发展了 DDA计算程序 ,分析了边坡大位移问题和地下开挖引起地面变形的工程实例 ,并与离散元计算结果进行了比较研究。
In order to ensure normal use of the near buildings under the influence of underground excavation,we need an accurate assessment on the influence of the underground excavating on the adjacent buildings damage.
