摘要
斜拉桥拉索的力学性质主要应用双曲线函数的悬链线理论和应用代数函数的抛物线理论作为分析的基础,采用抛物线理论简单方便,而悬链线理论更接近实际,精度更高。现以悬链线线理论为依据,精确计算拉索的参数,以及进一步的公式简化。简化公式更能体现斜拉索的物理意义,计算方便,便于工程上的应用。
The mechanical property of the stayed cable of cable-stayed bridge is mainly analyzed by the catenary theory of hyperbolic function and the parabola theory of algebraic function. The parabola theory is simple and convenient, and the catenary theory is more close to practice and is more accurate. Based on the catenary theory, the article accurately computes the parameters of stayed cable and further simplifies the formula. The simplified formula can reflect the physical significance of stayed cable better. The convenient computation is suitable for the engineering application.
