摘　　要：钢井架是矿山提升系统的核心构筑物。目前一阶弹性分析法仍然是广泛使用的一种钢结构稳定设计方法。本文采用欧拉公式和屈曲分析对斜撑构件的计算长度系数求解,利用分析软件MIDAS GEN对实际工程中的井架模型进行线性屈曲分析,并对计算长度系数求解过程进行详细介绍,可供类似工程参考。Steel headframe is a core structure of mine hoist system.Currently,first-order elastic analysis has remained the widely used method for steel structure stability design.The current standards only stipulate the value range of calculated length coefficient of the steel headframe diagonal braces without giving specific solution method.Euler's formula and buckling analysis can be used to solve calculated length coefficient of diagonal braces.The analysis software MIDAS GEN is used to perform linear buckling analysis on the headframe model in actual projects,with the procedure of solving calculated length coefficient introduced in detail,which can provide reference for similar projects.
