链杆法和有限元法计算弹性地基梁的比较与分析

Comparison and Analysis between Lingking-rod Method and Finite Element Method in Calculating Elastic Foundation Beam

本文以Boussinesq地基为地基模型,地基梁受均布荷载为例,分别采用有限元法和链杆法计算弹性地基梁的基底反力与沉降,并将两种方法的计算结果进行对比分析,研究其影响因素及两种计算方法的优缺点。

In this article, the contact pressure and sedimentations of some foundation beam under uniformly distributed load are calculated respectively via linking - rod method and finite element method based on the Bossinesq foundation model. At the same time, this article compares the calcultion rusuhs, and anlyzes the influence factors and the advantages and disadvantages of the above calculation methods.
