Force Analysis for Concrete Arch Dam Structure of Banjiang Reservoir

摘要

Concrete arch dam is the main structure of water conservancy projects, which have the advantages of a artistic shape of structure and good mechanical properties, and it has been widely used in water conservancy projects. Banjiang Reservoir is located in Zijiang River two tributaries of Dongkou County, Hunan Province, which is a reservoir to generate electricity, combined with irrigation water resources and hydropower engineering. This article gives the stress and deformation distribution during construction and operation which has done the simulation analysis for concrete arch dam structure of Banjiang Reservoir using the finite element method. The results show that Concrete Arch Dam Structure of Banjiang Reservoir satisfy the design requirements. Using concrete arch dam scheme of Banjiang Reservoir River is reasonable. Basically, circumferential stress of arch dam upstream face is compressive stress. Furthermore, the arch′s first principal stress which is small can meet the strength requirements, so the structure is safe and reliable.
