摘要
从人员、设备、环境及管理角度出发,建立瓦斯隧道施工风险评价体系。依托乘法原理与可拓层次模型,确定L隧道瓦斯风险等级。研究得出:L隧道风险等级评判结果为1.56,瓦斯涌出估算量为2.63 m^(2)/min,瓦斯绝对涌出量为1.79 m^(2)/min,隧道处于危险状态。最后,从施工通风、钻爆作业、电器设备与作业机械、瓦斯预测及监测方面给出危险处置建议。
From the perspective of personnel, equipment, environment and management, the risk evaluation system of gas tunnel construction is established. The gas risk level of L tunnel is determined based on the multiplication principle and extension hierarchy model. The results show that the risk grade evaluation result of L tunnel is 1.56, the estimated gas emission is 2.63 m^(2)/min, the absolute gas emission is 1.79 m^(2)/min, and the tunnel is in a dangerous state. Suggestions on disease treatment are given from the aspects of construction ventilation, drilling and blasting operation, electrical equipment and operation machinery, gas prediction and monitoring.
