倒T型环形基础的分析

ANALYSIS OF A RING FOUNDATION WITH UPSIDE DOWN T SHAPED SECTION

本文根据实际工程中大型双曲冷却塔的基础形状和受载方式,分析了倒T型环形基础的应力和位移分布。采用加权残差法求得了问题的解析解。文中提供了一个工程实例的分析,探讨了不同荷载形式和基础与土壤的剪切模量之比对于基础内应力分布的影响。

In this paper, the stress and displacement distribution of a ring foundation with upside down T shaped section are studied. In the analysis, an analytic solution of the ring foundation is obtained by the use of the weighted residuals method A numerical example is given. And the influence of the different combination of loadings and the different ratio of the shear modulus of the soil to that of the foundation upon the stress and displacement distribution of the ring foundation are investigated.
