摘要
利用三维拉格朗日有限差分法对某深埋隧洞工程进行分步开挖支护数值模拟,对比分析了隧洞在无支护、锚杆支护、衬砌支护及复合支护下围岩的应力、位移和塑性区分布,对地下隧洞工程设计与施工提供了参考依据。
By means of numerical simulation using Fast Lagrangian explicit finite difference method,the deep-buried tunnel has been analyzed by the step-excavation and supported with the different patterns. The effects of the different support patterns on the surrounding rock stability have been compared. The stress state, the displacement and the distribution of plastic regions have been analyzed. Finally,the useful results have been concluded, which will provide the references for actual projects.
