Simulation And Optimization On The Dam Construction Schemes Of Xiangjiaba Hydropower Station

Xiangjiaba hydropower station is located in the downstream of the Jinsha Riverand is the last one among the hydropower cascades on the Jinsha River. The dam ofXiangjiaba with the complex construction process is the critical point of the wholeproject, the construction scheme of which is related to the investment and theschedule of the whole project. The volume of dam's concrete is 8M m3 and theschedule is 66 months. Cable crane, Towerbelt crane, Portal crane and Tirebelt craneare involved. The optimization design of the construction scheme is important to theorganization and design of construction.The analysis of the scheme of dam construction concentrates mostly on theresearch on the combination of different cranes. The analogy method, namely makingthe plan by means of the experience of the other projects, is often adopted in thisprocess. Computer simulation of dam concrete construction system, which combinedHydraulic Project construction with modern compute methods ways, turned into thescientism field, such as simulation experimentation of construction process, numericalvalue analysis of construction parameter, optimization of construction scheme.The optimization of the dam construction schemes is researched based on thesystem analysis of the dam construction of Xiangjiaba hydropower station combinedwith computer simulation in this paper.The dam construction system of Xiangjiaba hydropower station consists ofproducing concrete, transporting concrete and pouring concrete. The system will rununder some restriction until the dam reach the top. Next the involved cranes areresearched and five schemes of dam construction are made. The five schemes areanalyzed with computer simulation and the optimized scheme is presented.
