　　为了探讨不同因素对矿井井塔剪力滞后效应的实际作用与影响，利用大型有限元分析软件，结合井塔的实际框筒结构进行建模分析。结果显示：角柱截面的变化对剪力滞后效应的影响很小，当角柱截面面积与其他柱的截面面积比在1.185～1.850范围内变化时对剪力滞后系数的影响可以忽略不计；梁柱刚度比的减小使得剪力滞后效应变得严重；结构长宽比L/B越大，剪力滞后效应越显著，在设计框筒结构的长宽比时，应尽量选择将结构布置成为长宽比L/B等于1.0或接近于1.0的设计方案，以减小剪力滞后现象对结构产生的影响，增强结构的整体性；随着结构开洞率的减小，剪力滞后效应的影响减少，且结构底部剪力滞后效应效果较为明显，随着结构高度的增加而呈逐渐下降的趋势，在结构设计时应尽量避免结构开洞过多。

In order to investigate the influence of different factors on the shear lag effect in mine tow-ers, the finite element software combined with the modeling of the frame-tube structure of a mine tower was used for analysis .The results show that the section change of the corner column has little influence on the shear lag effect within a reasonable range , and the shear lag effect coefficient can be ignored when the section area ratio of corner columns to other columns ranges from 1.185 ~1.850;the shear lag effect becomes serious with the decrease of the stiffness ratio of beams to col-umns.In the design of frame-tube structures, the ratio of length to width should be 1.0 or close to 1.0 so as to reduce the shear lag effect on the structures and enhance the integrity;the greater the length-width ratio is, the more shear lag effect occurs .With the reduction of the rate of holes , shear lag effect is reduced , and the shear lag effect on the bottom of the structure is more obvious and de-creases along with the height .Therefore , excessive rate of holes should be avoided in structure de-sign.
