摘　　要：针对复杂地质结构与多地质灾害风险的地下隧道开挖安全和科学施工,提出了一种隧道开挖计算机仿真方法。方法首先以地质勘探资料为基础,通过智能推演和人机交互方法进行三维地质建模,然后应用计算机仿真技术虚拟隧道开挖,最终揭示隧道围岩地质结构变化特征,实现隧道开挖过程中的地质灾害风险预警。方法成功地应用于几个大型铁路隧道开挖工程,结果证明该方法能够有效预测隧道围岩地质结构变化与地质灾害可能发生的空间位置、类型与级别。方法为实际隧道科学施工决策、安全开挖提供了可靠依据。We proposed an approach to simulate the tunneling process to ensure the safety of the underground-tunnel construction under complicated geological structure and risks of multiple geo-hazards. We first constructed the 3D geologi-cal model from the geological exploration data using intelligent deduction and human-computer interaetion approaches. Then we simulated the tunneling process to show the geological structure changes of the tunnel surrounding rock. In this way, we can predict the potential geo-hazards in the tunneling process. This approach has been successfully applied to several rail way tunneling projects. It is proved that it can effectively predict the changes of the surrounding rock, the location, type and magnitude of the geo-hazards. This approach could provide accurate information for tunnel construction.
