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.

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.

The three gorges project has successfully accomplished its closure work on Nov.8, 1997. At present the second stage work comes into construction and begin to place concrete in a large scale. The total quantity of concrete of the project approaches 15 million cubic meter. The cracking control of dam concrete is an important subject. By means of the optimization of cement, fly ash, aggregates and admixtures to make a good crack resistance concrete, and taking the measures of strict temperature control, pre-cooling the aggregates, reducing the concrete temperature at mixer and the placement temperature, and with a low heat of hydration to keep the highest temperature in the concrete blocks less than the assigned value, the harmful cracks will not occur when the temperature in the internal part of the dam decreases steadily. At the same time, through the thermal protection on the surface of dam, the surface cracking will be prevented. In general speaking, by means of optimization of raw material, specially, adding a lot of class I fly ash to reduce heat of hydration, and plus the strict cracking resistance measures in the whole process, to prevent the three gorges dam from harmful cracking can be realized.

china yangtze TGP is a particularly giant hydro development project in the world, with an enormous scale and complex technology. Seventy years project planning, verification and decision making and ten years construction work demonstrate that not only great progress has been made within the projects implementation stage, but most of the conclusions from the verifications and decisions are correct as well. Some problems like sedimentation, environment and resettlement are still waiting to be proven in the actual operation of the project. This paper provides a brief introduction to the decision making and practice on TGP.
