Effects of reservoir sediment on seismic response of concrete gravity dams

Arbitrary-Lagrangian-Eulerian finite element method is applied to simulate dam-water-foundation system with water as slightly compressible vicinal fluid and sediment as fluid-solid two-phase material.

Study on the controlled water levels of Three Gorges Reservoir in September with considering the impact of sediment deposition;

Impact on sediment deposition and shoals change in Chongqing Reach of the impounding water ahead of the schedule of the Three Gorges Reservoir;

Numerical model for effects of outlet shapes of approach channels on sediment deposition;

Analysis on influence of flow velocity-flow regime and sedimentation on operation of underground hydropower station of Three Gorges Project;

Study on water-sediment optimum allocation in upstream basin and comprehensive measures of sediment control in Guanting reservoirⅠ:Reservoir sedimentation and general plan of water and sediment control;

Research on sedimentation analysis based on GIS technique;

Study on sediment siltation for extension project of Weifang harbor;

By using wind,wave,tidal current,sediment numerical models based on the up-todata hydrology,sediment data of field observation and remote sensing data,sediment siltation in the deep channel is computed.

Based on a large quantity of meassured data,the pattern of sediment siltation is studied and the feasibility of building offshore deep water terminals in Tianjin Harbor is discussed as well.

Mathematical model of sediment scouring and silting in Naodehai reservoir;

The flow and sediment variation in the upstream of the Yangtze river,the sediment scouring and silting in the channel of the middle Yangtze river and their response relation were analyzed.
