文克尔地基上基础梁内力简化分析方法

Analysis and Simplified on Internal Forces of Foundation Beam on "Winkler Ground"

介绍了文克尔地基上基础梁内力计算的三种方法,即"有限长梁的叠加原理法"和通过查表求解的"设计简化法"及"有限元法"。通过实例计算对比,分析了"设计简化法"在基础梁内力计算中存在的误差和不足。随着计算机的应用普及,文克尔地基上基础梁内力计算应优先采用"有限长梁的叠加原理法"和"有限元法"。

In this paper, three methods are introduced for calculation of internal forces of foundation beam on Winkler ground, i.e. , ＂limited long beam combination principle method＂, ＂design simplified method＂ cal- culated by table and ＂finite element method＂. Through contrasted of calculation value of real example, the error and shortcoming on internal forces calculation value of foundation beam by ＂design simplified method＂ is stud- ied. In pace with application and popularization of computer, priority should be given to ＂limited long beam combination principle method＂ and ＂finite element method＂ in calculation of internal forces of foundation beam on Winkler ground.
