＜正＞ The Navier-Stokes flow analysis have been applied to successfully predicted flow characteristics and energy losses in different hydraulic turbine components. It has been used to design and optimize hydraulic turbine components. In this paper, the three-dimensional viscous flow is simulated through the whole flow passage of the model Francis turbine. The whole flow passage includes spiral case, distributor, runner and drafttube. The simulation is based on Navier-Stokes equations, the standard κ-εturbulence model and the SIMPLEC algorithm which is applied for the solution of the discrete governing equations. The velocity and pressure distribution through the whole flow passage of the model Francis turbine is attained. The energy property of the model turbine is then predicted and compared with the experimental datum.

＜正＞ The main dam of upper reservoir of Jiangsu Yixing pumped storage project, china, is a concrete face composite rockfill dam built on inclined foundation surface. The bedrock surface of the dam declines downstream with inclined angle of more than 2. degrees generally and even steeper than 30 degrees locally. The vertical height of the dam from downstream dam toe to dam crest is about 140m. Its stability and stress-deformation conditions are deferent from those of conventional CFRD. A systematic study on rockfill materials for building the dam was made during design. Two special issues, i.e. the shear strength between rockfill and bedrock, and the characteristics of settlement by wetting of rockfill composed of sandstone intercalated with mudstone, are described. Based on the study conclusion the main dam is filled by rock materials excavated in upper reservoir basin, and therefore dam cost is obviously reduced. Some rules revealed by studies may also be useful to design of similar dams.

＜正＞How to effectively solve the damage suffered from abrasion and cavitation in hydropower outlet works has always been one of the key research programs concerned by engineers of hydropower structures and materials since many years. This paper mainly described the excellent properties of a newly developed abrasion resistant organic-polymer materials-Spraying Polyurea （SPUA） Elastomer materials applied in hydropower works and the superior functions of its application technology. Furthermore, the primer with excellent properties suitable SPUA for the moist concrete substrate was investigated and the abrasion resistant test by scouring at high speeding silt-laden flow in the lab was performed. In comparison with the high strength concrete, the scouring results indicated the higher abrasion resistant ability of SPUA materials. In additional, the first practical applications of SPUA in the hydropower works were briefly introduced.

＜正＞A new rockfill creep constitutive model under high confining pressure is presented. The focus of the present development is on rockfill deformation development rule with time especially under high confining pressure, which is used the existing creep constitutive model derived from experimental data under low confining pressure up to now. In this paper many groups of triaxiality creep experimentation with different high confining pressure are carried out. All experimentation data shows good regulariy very much. The rockfill shear creep and the volume creep with time may be expressed by power function. The new final creep model is function of specific stress state. It improves the disadvantage of the old final shear creep model, which is only function of stress level and yet does not include the influence of confining pressure. The new final shear creep and volume creep model are deduced in detail from triaxialiry creep experiments’ curve under different high confining pressure. Numerical realization step and algorithm applied to the analysis of general FEM is also presented for the new creep model. The performance of the new creep model is assessed against experimental data from numerical simulation results of riaxiality creep experiment and it is concluded that the new creep model is able to represent the key and real characteristics of the behavior of rockfill creep. It can also be applied directly to the analysis of deformation and stress of high CFRD.
