摘　　要：本文以一个淋水面积为5500m^2大小的冷却塔为例,通过改变冷却塔建模中底部弹簧刚度的大小来分析当环基底部地基刚度逐渐增大时,环基内力在主要荷载—自重、风荷载、温度荷载作用下的变化情况,并得到一些有益的结论。Taking one cooling tower whose filling area is 5500 square meters as an example, the changes of the forces of foundation ring beam were analyzed when the subsoil stiffness under the foundation ring beam was changed, and the cooling tower is subjected to the main load, such as self weight, wind load and temperature load. Some useful conclusions have been got.
