弹性地基上矩形水池底板的计算分析

Structural Analysis of Rectangular Pool Floor Lying on An Elastic Foundation

本文利用弹性地基梁的直线分布模型、文克尔模型、弹性半无限体模型及有限压缩层模型对地基上矩形水池底板进行计算。在传统的计算方法与理正弹性地基梁分析软件的基础上,使用后三种地基线弹性模型对矩形水池底板在集中荷载和均布荷载的作用下进行计算。在找出各个模型的优缺点的同时,对矩形水池底板的两种计算结果进行对比,以便在以后的工程实际中更合理的使用地基线弹性模型和计算方法。

A rectangular pool floor lying on an elastic foundation is calculated with the linear elastic foundation beam model,Winkler model,elastic semi-infinite volume model and finite compression layer model.Based on traditional calculation methods and a elastic foundation beam analysis software ＂Lizheng＂,the latter three foundation linear elastic models are used for the calculation of rectangular pool floor under the concentrated load and uniform load,respectively.In order to adopt the foundation linear elastic model and calculation meth- ods more rationally in future engineering practice,the results of rectangular pool floor under the concentrated load and uniform load are compared while the advantages and disadvantages of each model are identified.
