本文运用“G—M法”的基本原理,将曲线梁桥比拟为正交异性曲板,通过求解微分方程,导出计算荷载横向分布的一般公式。为了便于实用计算,本文参照“G—M法”编制了计算荷载横向分布影响系数的曲线图表,并辅以几个参数的内插公式。文中还指出刚性横梁法的适用范围。本文的理论曾用有机玻璃模型进行试验,得到验证。
In this paper, the basic principle of “G-M method” is used to compare curved beam bridges to orthotropic curvature plates. By solving the differential equations, the general formula for calculating the lateral distribution of load is derived. In order to facilitate the practical calculation, this paper refers to the “G-M method” to compile the curve chart of the influence coefficient of the lateral distribution of load, and it is supplemented by the interpolation formula of several parameters. The paper also points out the application of rigid beam method. The theory of this paper has been tested using organic glass models and verified.
