摘要
在分析采准巷道U型钢可缩性支架的工作阻力、可缩性和整体稳定性的基础上,本文提出U型钢截面设计原则,给出设计时所需计算公式,阐述校、核设计的方法,提供新型25U型钢截面图纸,供生产新型25U型钢时使用.
Based on the analysis of the working resistance, yieldability and lateral stability of U-steel yieldable roadway support in situ, the paper puts forward some principles of reasonable section design of U-steel used for roadway support, gives formulae for calculating the geometrical parameters of the section. The method for checking calculation is explained, and the drawing of section of a new type 25U-steel is provided.
