Abstract：
The fitting method of lateral deformation curve was put forward from the theory and then the curve of diaphragm wall moment was calculated by fitting curve. To validate the fitting method , the inclinometer tube and stress gauge are buried in the same diaphragm wall. The deformation curve and the moment of diaphragm wall are tested after excavation. The fitting moment and the measured moment were comparing analyzed, the results showed that the fitting moment was agreed with the measured moment.
