＜正＞For the Hongjiadu CFrD with the height of 178.5m, numerical method and centrifuge modeling test are used for analysis the stress and deformation properties of high CFrD in narrow valley. Under the condition of unsymmetrical narrow valley, the stress and deformation distribution of the dam and the displacement of joints during dam construction and reservoir impoundment are presented from the analysis. And also, the impact of the of rockfill density variation on the stress properties of the slab is analyzed. The research results show that: the shape of river valley has significant impact on stress and deformation status of CFrD. By improving construction technology and increasing filling density, the stress and deformation properties of CFrD could be improved.

＜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 20 degrees generally and even steeper than 3. 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＞ 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＞Hongjiadu （HJD） hydropower project which is located in the northern source of the main stream of the Wujiang river is the head hydropower station in the cascade projects of the Wujiang river. It is also one of the start-up projects among "west-electricity transmitted to the east" items. The gate of the diversion tunnel will be dropped down in April, 2004 and a generating unit will firstly generate electricity in July in the same year. The hydrostructures of the project consist of a dam and the structures on the left bank which conclude a spillway, a tunnel spillway, power conduit system, a power house and so on. The damsite is located in the high mountainous region with narrow valleys and karst, and the height of the dam is 179.50m. It is one of the highest concrete faced rockfill dam （CFrD） that is under construction in the world. The dam has been embanked 13.m added up 7.0 million m3.at the present time and it underwent twice tests in 2002 and 2003.flood season respectively. The dam will experience the test of water storage in 2004. New technologies, such as narrow continuous plinth with equivalent width and impact compaction by LAND pac, are adopted in the dam design and construction of HJD CFrD. The article presents the design and construction technique of HJD CFrD.

＜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.
