西霞院泄洪闸三维有限元应力分析

Three-dimensional Finite Element Stress Analysis of Flood Sluice in Xixiayuan Project

西霞院开敞式泄洪闸结构采用普通钢筋混凝土,边墩较薄,结构受力条件复杂。为全面了解闸室结构受力情况,确保泄洪闸结构的安全运用,采用三维有限元计算模型,通过各运用工况下闸室的应力分析,研究可能产生的裂缝部位和应采取的措施,得出了结构的合理配筋。

Steel-reinforced concrete is used in the structure of the open flood sluice of Xixiayuan, its abutment is thin, and its stressed conditions of structure are complicated. To understand the stressed situation of the gate structure and ensure the safety operation of the flood sluice structure, by using the computation model of three-dimensional finite element, and through the stress analysis of the gate under various operating conditions, the locations at which cracks might appear and the measures which should be taken are studied, and the reasonable reinforcement for the structure is worked out.
