In order to solve the problem of differential settlement, seepage flow and stability between the new and old dam boundary in capacity increasing of the plain reservoirs, the comparative analysis on the stability of the dam slope with different methods on dealing with the new and old dam boundary was performed by numerical simulation with FLAC3D. The result shows that combining the new and old dam by using geogrid indicates superiority for reducing differential settlement, improving the dam stability and safety, etc. In the meantime, on the basis of actual site investigation and theoretical analysis, combined with the requirements of design, construction and management in capacity increasing of the plain reservoirs, the key construction technology was put forward and widely applied foreground, which can improve the quality of the construction, reduce engineering disease and provide references for capacity increasing engineering of in plain reservoirs.

One major concern for excavation projects is the ground displacement generated around the excavated zone. In this paper, a 2-dimensional model analysis was made on non-linear ground behavior around excavation due to unsteady seepage of groundwater, taking into account the saturated-unsaturated theory by using Toyo-ura sand. The finite-element method and finite-different method were employed to study the space problem and time dimension, respectively. The numerical simulation code implemented by FORTRAN was applied to predict the flow-velocity distribution and the results of ground displacement. To validate the programming, a simple model was tested for comparison with tri-axial test data. The samples were made of Toyo-ura sand with a relative density of 90%. The programming also calculated flow-velocity distribution and ground displacement results of dewatering in excavation work over time. Results showed that the effect of horizontal displacement caused by seepage flow plays a very important role in the displacement field. This numerical simulation method provides a more reasonable computing scheme compared to traditional methods. All have theoretical meaning and applicable value, and also present useful references for the excavation stability and disaster prediction.
