This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

For the first time, a screw pile and pile driver system for preventing flood and rushing to deal with an emergency was manufactured. The screw piles of the system is different from screw drills used to sap, and it doesn't push soils out. Analyses, including the screw pile's structural strength analysis and the screw blade's welding analysis, were done by ANSYS, which showed that the screw pile's structural strength is enough and that the distort of the screw blade is small. Testing on the screw pile and pile driver system showed that the system performed stably and could meet the need of preventing flood and rushing to deal with an emergency. A mechanics model of interaction of a screw pile and soil was built, and expressions of torque of screw pile's cylindrical part on the condition of screw pile's crew part being driven into soil fully were gained, then the relation of the torque with screw pitch and out diameter of cylinder, which shows the torque decreases with the screw pitch increasing, and that the torque increases with the out diameter of cylinder increasing, which was according with the experiments of the screw pile's being driven into soils, and thus a screw pile with the best structure was chosen. Experiments of bionic surface showed that, on the condition of certain pressure on the surface, the protruding bionic surface can not reduce adhesion and resistance and that the corrugated bionic surface can reduce adhesion and resistance. An orthogonal experiment of the corrugated bionic surface was done with the factors including the width of protrusion, the space between two protrusions, the trolley's velocity and the vertical surface pressure and with the surface frictional coefficient as the experimental target, and some inclusions were drawn that the best combination of the factors was acquired and that the width of protrusion affected the surface frictional coefficient remarkably.
