U29型钢支架的偏载对承载能力的影响分析

Analysis of Effect of Partial Load of U29-steel Brackets on Bearing Capacity

通过理论分析与Ansys数值模拟比较U29型钢支架在矿井巷道支护过程中均载和偏载2种条件下,支架的拱部、肩部和帮部表现出不同的承载特点来研究偏载对支架承载能力的影响,为实际工程应用提供参考,使支架达到最佳的支护效果。

To study the effect of partial load on bracket supporting capacity in order to provide a reference for practical engineering applications and achieve the best possible supporting effect by comparing the different load characteristics of vaulted,shoulder and lateral sections of U29-steel brackets under the two kinds of conditions of uniform load and partial load in the mine tunnels through theoretical analysis and numerical simulation of Ansys.
