Abstract

The prediction of foundation pit deformation is of great significance in ensuring the safety of neighbors and efficiency of construction. The back-propagation neural network (BPNN) is one of the most successful models that have been implemented for data prediction. An accurate mapping relationship cannot be constructed by directly applying neural networks due to the measured data of foundation pit suffer from small quantity and big noise. In the present study, the main idea of residual network (ResNet) was introduced in prediction, and genetic algorithm (GA) and back propagation (BP) were coupled to develop a hybrid GA-ResNN training algorithm with global search capabilities. The dimension of the input data is doubled by overlapping and encoding the input data. The dependence of the neural network on the initial model can be reduced using GA and ResNet. Cases reported in the literature are used to demonstrate the effectiveness and accuracy of the proposed model.
