摘要
浅埋暗挖隧道工程施工具有许多不确定性风险因素,需要对风险事件进行安全等级确定和风险优先排序。采用模糊逻辑与失效模式影响分析、故障树分析和层次分析法-数据包络分析相结合的方法,提出浅埋暗挖隧道工程施工风险综合评价新方法,可为浅埋暗挖隧道施工风险重要事件的筛选提供一种实用、合理的方法。将该方法应用于广东金光东隧道浅埋暗挖矿山隧道工程的施工风险评估,结果表明:洞门破除土体失稳风险和对周边环境风险(古树、电塔等)优先级RPN值均>0.4,且<0.55,风险等级为2级,因此,针对这些风险事件需要采取风险控制措施进行预防。其他风险事件的风险等级为3级,风险可接受,可采取安全控制措施。
There are many uncertain risk factors in the construction of shallow buried tunnels.It is necessary to determine the safety level and prioritize the risk events.In this paper,a new comprehensive evaluation method of construction risk of shallow-buried tunnels was proposed by combining fuzzy logic with failure mode impact analysis,fault tree analysis and analytic hierarchy process-data envelopment analysis.It can provide a practical and comprehensive method for screening important risk events of shallow-buried tunnels.The method was applied to the construction risk assessment of shallow-buried tunnels in Jinguangdong Tunnel.The results show that the risk of instability of the tunnel entrance and Shallow-Buried Section and the priority RPN value of the surrounding environmental risk(ancient trees,electric towers,etc.)are>0.4,and<0.55.The risk level is 3.Therefore,appropriate mining is needed for these risk events.Take corresponding control measures to prevent.The risk level of other risk events is 2,and the risk is low,so some safety control measures can be taken.
