Intelligent control of deformation during excavation for large and deep foundation

This paper discusses application of artificial neural networks and fuzzy logical theory to control the deformation of diaphragm wall and ground settlements during excavation for large deep foundation. Based on MATLAB 5.2, an intelligent control system for safety of large foundation excavation was developed. The system has been tested on a large soft soil foundation excavation project in Shanghai. The results showed that the control system is very effective as a means of intelligent control for deformation of soil and diaphragm wall during foundation excavation.
