| Abstract: | Based on the contact Element Method,nonlinear equations for the analysis of the miter gates of the Three Gorges Project are established.The variations of the contact area and stress and displacement of the miter gates during water level rise and fall are studied.A simple and valid method to overcome the effect of the displacement of the lock wall through adjusting the prestress of the back drag rod is presented. |
