摘要: 为解决煤矿井下车辆循环重载引发道路结构破坏,从而影响巷道底板的稳定性,威胁安全生产的问题。采用有限元软件模拟方法分析李家壕煤矿混凝土巷道底板在无轨胶轮车移动荷载作用下动力响应,探究巷道无轨胶轮车动力荷载对李家壕煤矿混凝土巷道的影响。首先,运用ABAQUS软件模型对李家壕煤矿巷道底板进行建模;然后,分析车辆移动荷载作用下李家壕煤矿巷道底板模型中不同位置的竖向位移以及应力的动力响应;最后,探究不同轴载下李家壕煤矿巷道底板最不利位置的动力响应。结果表明:不同轴载下,面层顶面竖向位移与基层底面水平应力为最不利动力响应位置,这为李家壕煤矿巷道混凝土道路结构设计提供了指导。

Abstract:

In order to solve the problem of road structure damage caused by cyclic heavy load of underground vehicles in coal mines, which affects the stability of roadway floor and threatens safety production, the finite element software simulation method was used to analyze the dynamic response of the concrete roadway floor of Lijiahao Coal Mine under the moving load of the trackless rubber-tyred vehicle. The influence of the dynamic load of the trackless rubber-tyred vehicle on the concrete roadway of Lijiahao Coal Mine was determined. First, ABAQUS software was used to model the roadway floor of Lijiahao Coal Mine; then, the dynamic response of vertical displacement and stress at different positions in the model of the roadway floor of Lijiahao Coal Mine under the action of vehicle moving load was analyzed. Finally, the dynamic response of the most unfavorable position of the roadway floor of Lijiahao Coal Mine under different axle loads was explored. The results show that the vertical displacement of the top surface of the surface layer and the horizontal stress of the bottom surface of the base layer are the most unfavorable dynamic response positions under different axial loads, which provides guidance for the design of the concrete roadway structure of the Lijiahao Coal Mine.

Key words: roadway floor, dynamic response, moving load, ABAQUS, vertical displacement
