The turbulence flow Free Surface has important applications in hydraulic spillways structure, such as the hydraulic jump, energy dissipation flow etc. This is being considered as very complicated flow, and has not yet been solved quite well by numerical method. In this paper, a Large-scale computational software package are developed for numerical laboratory of hydraulic spillway structure. Some methods,such as turbulence model, free surface and irregular boundary treating techniques,scientific computer visualization are put forward and performed.

The Three gorges project （TGP） is the largest water conservancy and hydropower complex in the world, with a concrete consumption of 2. million m3in total. For such a significant world-attracting project, first rate quality concrete is needed. Various mechanical and deformation performances of hydraulic mass concrete are determined conventionally by the wet screening method to make small specimens and the test results of the small standard specimens are taken to represent the properties of the mass concrete. However, the quantity of the coarse aggregate after wet screening would be reduced by 30% or so and the gel materials would increase by 2.% or so, thus causing significant differences between the properties of the small concrete specimen and that of the total gradation concrete. To well understand the performances of the total gradation concrete of TGP dam, test studies have been performed on the total gradation concrete, including compressive strength, split tensile strength, elastic modulus, ultimate tension, dry shrinkage, self volume deformation, creep, seepage prevention, and so on, and comparison made with the small standard specimens to find out the relationship between them, which have provided scientific ground for the design, operation and safety verification of the TGP dam.

To solve the high dam navigation issue of a world class project is one of the key technical issues that bring many difficulties upon the Three gorges project (TGP). Special requirements exist in the TGP double lane five step shiplock in terms of a general layout of navigation structures, a sedimentation hindrance to navigation, hydraulics of the water conveyance system, treatment of high and steep slopes, the manufacture and technology of both main metal structures and mechanical and electric equipment, all of which have been resolved step by step by means of scientific tests, verification and engineering practice.

In this preliminary study, it is shown that for a reservoir on a river of rich runoff like the yangtze of a rich runoff, an elaborate scheme of sediment management may be devised to substantially reduce the reservoir deposition. The mathematical model applied in this investigation has been fairly well verified with the long term field data on the sediment transport by an unsteady flow in the lower Yellow river. In view of the importance of TGP, however, a further investigation with physical models and mathematical models of other versions is planned. Great financial benefits are involved.
