| 摘 要： | 大临铁路红豆山隧道1#斜井采用“斜井+平导+正洞”多作业面施工的组织方式,在施工中检测到多种高浓度有害气体,给施工通风及管理提出了极高要求。通过优化通风设计,建立基于有害气体监测的多作业面隧道通风管理系统,依据有害气体浓度和风速变化情况,控制移动式风扇的位置、主通风机的送风量及局扇的运行状态,并通过通风可靠性评价,实现有害气体的全过程、全方位监测和隧道通风的安全动态管理,对类似隧道通风管理提供参考。

| Abstract: | In the construction of 1#inclined shaft of Hongdoushan Tunnel of Dali-Lincang Railway under the organization mode of"inclined shaft+parallel heading+main tunnel",many kinds of high-concentration harmful gases have been detected,which impose extremely high requirements for ventilation and management of construction.Through the optimization of ventilation design,the ventilation management system for multiworking face tunnel based on harmful gas monitoring was established.The positions of mobile fans,the air supply volume of main ventilators and the working state of local fans were controlled according to the change of harmful gas concentration and air speed.Based on the evaluation on ventilation reliability,the whole-process and all-round monitoring and safety dynamic management of tunnel ventilation have been realized,which is of referential significance for the ventilation management during construction of similar tunnels. |
