模糊聚类分析在隧道围岩稳定性预测中的应用

应用模糊聚类理论,通过对杭新景高速公路隧道监测历史数据进行的聚类分析,依据模糊聚类和模糊模式识别、类别变量特征值与概率统计相关分析等模型,根据模糊聚类参数与预测因子的前期特征值,确定相应的类别变量特征值,建立类别变量特征值与预测对象之间的相关关系,利用此相关关系对隧道拱顶沉降速率进行了预测,从而判断围岩的稳定情况。

The application of fuzzy cluster method for the forecast of the rock stability

Using fuzzy cluster theory,through the cluster analysis of the historical data of tunnel monitoring of Hanxinjing expressway and on the basis of the fuzzy cluster,the fuzzy pattern recognition,the eigenvalue of class variable,and the corresponding class variable is determined according to the fuzzy cluster parameters and prophetic eigenvalue of forecasting factors,then the correlative relation among the eigenvalue of class variables and the forecasted objects is established and the deformation speed can carry out by use of this correlative relation.
