摘要
应用灰色系统理论对软岩巷道开巷初期围岩变形进行了预测 ,通过实例说明用GM( 1 ,1 )模型和双向差分模型预测巷道的围岩变形都是简单可行的。对GM ( 1 ,1 )模型进行了改进 ,建立了具有较小原点误差的改进的GM ( 1 ,1 )模型 ,并且给出了双向差分模型、GM ( 1 ,1 )模型与其改进模型对软巷道围岩变形预测结果的比较 ,为灰色系统理论用于软岩巷道开巷初始围岩及支扩变形预测的实践进行了新的探讨 。
Applied the Gray System Theory, deformation of soft rock around tunnels in the initial period of tunnel excavation was studied. It is proved that GM (1,1) mod el is suitable. An improved GM(1,1) model is buil, which has less original error . The prediction results for the three kinds of models are also compared. The st udy presents a new way for predicting the deformation of soft rock around tunnel s as well as support in the initial period of tunnel by using Gray System Theory . It will play a great part in the prediction of the soft rock engineering.
