| Abstract: | The study on rock mass deformation of middle isolated pier (MIP) of the second permanent shiplock is discussed. The time series analysis and grey system theory are used to predict the tendency of rock displacements of MIP based on in situ measured data. The comprehensive results can be summarized as follows: (1) the horizontal displacement vertical to axial line of shiplock varies with process of excavation, and is in steady state after excavation; (2) the horizontal displacement parallel to axial line of shiplock is of tendency of developing to downstream; and (3) the vertical displacement has the property that resilient deformation occurs during excavation, and then subsidence with slightly various values takes place in different parts of the middle isolated pier. |
