DEEP EXCAVATION MULTI-POINT DISPLACEMENT MONITORING MODEL AND DETERMINATION OF RBF CENTER BY FCM
-
摘要: 为建立合理的基坑多测点位移监测模型,采用径向基函数神经网络(RBF)为基本框架,从位移力学机制选择网络输入层,以相关联的多个测点位移为输出层,发挥RBF网络非线性映射功能的同时,根据基坑的开挖进展和位移特征,采用有针对性的预选RBF计算中心与模糊C均值聚类(FCM)算法,共同确定计算中心。实例表明,该计算方法更具合理性,且能获得理想的训练和预测效果。Abstract: To establish reasonable deep excavation multi-point displacement monitoring model,radial basis function artificial neural network(RBF)was taken as frame.Its input layer came from displacement mechanical theory,and output layer was formed by interrelated multi-point displacement.Considering excavation and displacement characteristics,special preselecting RBF centers and Fuzzy C-means Algorithm(FCM)were used together to confirm RBF centers.Instances showed that these methods were more reasonable and possed good training and forecasting results.
