Artificial Neural Network´s Application in Intelligent Prediction of Enclosure Structure Deformation Induced by Foundation Pit Excavation

Enclosure structure deformation induced by foundation pit excavation is one of important problems in foundation pit engineering. The factors influencing the enclosure structure deformation are complex and have stochastic and fuzzy properties, which have brought difficulties to the enclosure structure deformation prediction. The traditional methods are obviously inadequate while being used to predict the enclosure structure deformation. In this paper, the intelligent prediction method based on BP artificial neural network (ANN) and multi-step circulation is established and can solve these problems. Practices show that the accuracy of the method can meet the application requirements; the method has a few features, such as, with high efficiency, use of convenience, suitable for engineering applications, and so on, and has certain engineering and technical value.
