有限元数值模拟在斜坡道施工开挖中的应用

Application of finite element numerical simulation in ramp construction

在现有巷道围岩稳定性研究及地下工程施工开挖过程数值模拟理论和分析方法的基础上,通过分析斜坡道施工过程中引起的围岩应力、应变状态及支护结构力学行为变化过程,获得了围岩应力和位移变化规律,为斜坡道的施工设计、安全管理提供理论依据。

On the basis of stability study of present roadway surrounding rock and the theory and analysis method of numerical simulation of underground engineering excavation, through analyzing the change process of rock stress, strain state and supporting structure mechanics during the ramp construction, the variation of rock stress and displacement were obtained. Those results can provide theoretical support for ramp working design and safety management.
