摘要
隧道突泥涌水容易造成人员伤亡,经济损失和环境破坏等不利影响。针对目前隧道建设过程中现有突涌水风险评估方法在动态评估方面研究不足的问题。文中通过典型案例收集,总结隧道施工前和施工过程中突涌水的主要风险源和评价指标。基于层次分析法给出相关指标权重。提出施工阶段动态更新指标值的方法通过将研究成果集成于小程序中,在实际工程中得到了应用,结果有效规避了风险,保证了施工安全。
The risk of mud and water inrush in tunnels will cause serious casualties, economic loss and environmental damage. Aiming at the problem of insufficient research on dynamic evaluation of existing water inrush risk assessment methods during tunnel construction, this paper summarizes the main risk sources and evaluation indicators of water inrush before and during tunnel construction by collecting typical cases. Based on the analytic hierarchy process, this paper gives the weight of relevant indexs. The method of dynamical updating index value in construction stage is put forward. By integrating research results into small programs, it has been applied in practical projects, and the results can effectively avoid risks and ensure construction safety.
