Abstract:
Through collecting and investigating a large amount of hydrology , geology , water resources, and engineering technical data, the paper discusses the optimization of the western route project scheme, and puts forward the main problems faced by the eng ineering research on the basis of the existing research; using the multi-index comparison method, starting from the water diversion section downward moving gravity flow scheme and pumping scheme of the west line project , discuss the pros and cons of the plan th rough indicators such as the adjustable river water volume, environmental impact, resettlement scope, investment cost and economic benefit, and demonstrate the feasibility and superiority of the project shifting the gravity flow plan. Simultaneously , in order to reduce the impact of water transfer on ecology , environment, society and other aspects, the Jinsha River, Ya long River , and Dadu River have been analyzed and drafted for an average annual water transfer volume of 17 ×109 m3 . The research results can provide an important technical basis for future engineering construction decisions.
