摘　　要：随着现代科技进步,矿山开采往深部发展。面临着开采强度的增大,U型钢支架也在更多的场合发挥作用。通过ANSYS软件对U型钢支架在对称非均布载荷、腿部偏载、肩部偏载等载荷作用下受力变形特征进行数值模拟,研究了支架顶部及两帮的位移变化曲线,对支架选型、设计及改进提供了依据,对控制围岩变形以及维持巷道相对稳定有重大意义。With the development of modern technology, depth of the mines becomes deeper. Faced with increasing strength, more and more U-steel brackets are used in the various major coal roadway support. Through using ANSYS numerical simulation, the paper makes research on U-steel with the computer imitating, including kinds of situations. It provides according to the choices and designs and improvements of the supports, which has a vital effect on the control and stabilization of roadways.
