[提要]  铁矿井塔属于重载高层构筑物，为探讨强度和稳定性，利用异质模型，国内不少单位用力学手段进行过许多研究，由于泊松比不一致，给实验带来误差。本文针对一井塔，利用钢筋混凝土同质模型，对井塔进行了强度、稳定性分析，为工程设计提供了重要资料。

The headframe of iron mine belongs to the heavy load and high layer construction. In order to approach strength and stability, some domestic researchers did a lot of studies using the heteroge-neous model by the mechanic method.  But, there were some experimental errors owing to poisson's ratio was not identical. In this paper, using the homogeneous model of the reinforced concrete, the strength and stability of the headframe are analysed, which provided important data for the engineering design.
