摘要
采用ANASYS有限元软件对超深陡峭岩壁脚手架受竖向和水平荷载作用下屈曲模态进行了分析,根据研究可知:连岩件采用错列式分布相比并列分布承载力要大;随着模态的升高最大位移节点的高度也随着升高,脚手架的变形呈现出底部横向扭动的趋势,整个脚手架的薄弱点是脚手架底部,可以通过加固脚手架底部刚度来提升整个脚手架的极限承载力。本文研究内容可为类似工程起到指导作用。
According to the research, the following conclusions can be drawn. The rock mass with the staggered rock-column scaffolding is compared with the parallel distributed bearing.With the increase of the mode, the height of the maximum displacement node will increase with the height of the scaffold. The deformation of the scaffolding shows the tendency of horizontal wriggling at the bottom. The weak point of the whole scaffold is the scaffold bottom, bottom stiffness to enhance the ultimate bearing capacity of the entire scaffolding. The research work in this paper can be used for similar projects.
