摘要:

双曲线型冷却塔是电力工业中的重要构筑物,它的可靠程度直接关系到电力生产的稳定与安全.结合某火电厂双曲线型冷却塔的可靠性鉴定,根据双曲线型冷却塔的结构特点,建立了由梁元和壳元组成的结构模型,采用有限元方法对双曲线型冷却塔在各种荷载组合作用下的受力进行了分析计算,提出了这类工业构筑物的可靠性分析与鉴定方法.分析计算结果表明,这种方法系统、全面,符合结构实际,同时可以考虑结构损伤对结构受力性能的影响,并已应用于工程实际.

Abstract:

Hyperbolic cooling tower is an important structure in the power industry, and its reliability is directly related to the stability and safety of power production. Combined with the reliability identification of a hyperbolic cooling tower of a thermal power plant, according to the structural characteristics of the hyperbolic cooling tower, a structural model composed of beam elements and shell elements was established, and the force of the hyperbolic cooling tower under various load combinations was analyzed and calculated by the finite element method, and the reliability analysis and identification method of such industrial structures was proposed. The analysis and calculation results show that this method is systematic, comprehensive and in line with the structural reality, and can consider the influence of structural damage on the stress performance of the structure, and has been applied to the engineering practice.
