The prediction of vertical ultimate bearing capacity of single pile constitutes one of the problems most frequently encountered by geotechnical engineers.In this paper,the vertical ultimate bearing capacity of single pile has been studied by using FEM as numerical method.The static test of single pile has been simulated by using ANSYS.By taking the back-calculation process on Q~s curve of single pile loading test,the GA-ANN method is introduced to predict vertical ultimate bearing capacity of single pile by...
