摘要
爆破冲击波理论研究复杂,不确定性因素较多,为减少钻爆法施工爆破冲击波对人员和设备的伤害,有必要对隧道爆破冲击波进行安全风险评估。以福建某高速公路隧道为依托,结合相关规范和文献,对爆破冲击波风险进行了有效的风险识别,建立了隧道钻爆法施工爆破冲击波风险评价指标体系。将灰色关联度理论引入模糊层次分析法,建立了隧道爆破冲击波风险评估模型。根据定量计算结果分析,结合建立的评价集,可以得到爆破冲击波风险发生的概率等级。由评估得到的各指标关联度大小,可采取相应的措施来降低爆破冲击波带来的风险。该爆破冲击波评价体系和评估模型可供类似工程参考借鉴。
The theoretical research of blast wave is complex and uncertain. In order to reduce the damage of blast wave to personnel and equipments, it is necessary to evaluate the safety risk of tunnel blast wave. Based on a highway tunnel in Fujian, the blast wave risk was effectively identified by combining relevant specifications and literature, and a blast wave risk evaluation index system of tunnel drilling and blasting method construction was established. Combining Grey Relational Analysis with Fuzzy Analytic Hierarchy Process, a tunnel blast wave risk assessment model was established. According to the analysis of quantitative calculation results, the corresponding risk grade of tunnel blast wave in the evaluation set could be obtained. Depending on the correlation degree of each index obtained from the evaluation results, corresponding measures could be taken to reduce the risk of the tunnel blast wave.The evaluation system and model can be used as reference in similar projects.
