Abstract
The selection of dam site is the key content in the early stage of hydropower station project. Based on the hydrology, topographic and geological conditions, kinetic energy economic indexes, flood loss of reservoir, project layout, electromechanical and metal structure, construction conditions and project investment of the proposed dam site, this paper makes an in-depth analysis of the dam site selection in the pre-feasibility stage of Shitouzhai Hydropower Station, in order to provide beneficial inspiration for the design of similar projects.
Highlights
The selection of dam site is the core link of hydropower project design[1]
Shitouzhai Hydropower Station is located at 30.8km of the highway road along the downstream of Liuku, Nujiang Prefecture, Yunnan Province, and 7km downstream of Shangjiang Township, Nujiang Prefecture
Shitouzhai Hydropower Station is about 35km away from Liuku Hydropower Station in the upstream, and main submerged objects of the reservoir area are the settlements across the River from Liuku Town and Wanqiao Village, the farmland and villages along the river in Shangjiang Township, The New village of Baili and the secondary highway from Jinchangling to Liuku
Summary
The selection of dam site is the core link of hydropower project design[1]. The reasonable selection of dam site is conducive to ensuring project safety, shortening construction period and reducing construction investment. It is of great significance to compare and select dam site at the initial stage of engineering construction[2]. Based on the preliminary feasibility study stage ShiTouzhai hydropower Station dam site selection, for example, plans to choose from ShiTouzhai hydropower project dam site hydrology, topography and geological conditions, the kinetic energy of economic indicators, reservoir inundation loss, engineering layout, mechanical and electronic and metal structure, construction conditions and investment aspects of a comprehensive economic and technical comparison, the final selection of dam site recommend dam site for preliminary feasibility study stage
