摘要: 简要介绍了弹性地基梁内力计算常用的几种方法,推导并修正了双参数解中的弯矩解析式,在双参数解的基础上,令地基剪切系数为零,得出了初参数解。依托工程案例,采用海藤尼法、无限长梁法、初参数法、双参数法四种方法分析了有限长梁在多个集中力作用下的内力变化规律,得出了地基剪切系数对框架梁内力及位移的影响,期望能为锚索框架梁内力计算提供一定的参考。

Abstract: This paper introduces several conventional internal force estimation methods of the beam on elastic soils. The bending moment formula in the Two-Parameter Method is improved and the new internal force solution is obtained by assigning zero coefficient of foundation shearing in the beam on elastic soils. Four different approaches of obtaining the internal forces in a real project application and these methods are: HetenyiMethod, Infinite Beam Method, Initial Parameter Method and Two-Parameter Method. The impact of foundation shear coefficient on the internal forces in beam on elastic soils are also evaluated.

Key words: AnchoredFrame Beams, Internal Force Analysis, Initial Parameter Method, Two-Parameter Method
