摘要
柱下条形基础是常用于软弱地基上框架或排架结构的一种基础类型,目前大多计算柱下条基所采用的方法是温克尔地基梁模型.采用双参数地基模型来改进温克尔地基模型,并用有限差分的方法求解任意荷载下条基的微分方程,得到便于工程计算的线性方程组.通过变换参数和荷载进一步研究参数和荷载对条基挠度的影响,探讨地基与基础的共同作用的一般规律.采用双参数的理论较温氏模型更为完善,也更符合地基受力、变形特点.
Nowadays, linear basis under columns is solved by Winkler model. Take double parameters foundation model to improve Winkler model, and use finite difference method to resolve linear basis under columns and get linear equations which could be easily used in works. We can further discuss the influences of the parameters and the load of the linear basis under columns by changing them regularly, and analyze the regulation of the interaction of foundation and the beam. This method is more useful and realistic than the former one.
