摘要
陡倾边坡下隧道洞口段施工风险评价是隧道工程灾害防治的关键任务,科学合理地评估隧道施工风险至关重要。文章以济新高速公路项目峡里隧道为例,引入最优传递矩阵来计算影响隧道洞口段施工风险评价指标的权重排序,同时结合突变理论,通过对评估指标值进行无量纲化处理,并根据权重排序进行归一化处理,得到了总体的突变级数值。通过对改进AHP-突变理论综合评估和实地调查结果进行对比,发现结果基本一致,验证了该方法在隧道洞口段施工风险评估中的可靠性。
The construction risk assessment of the tunnel entrance section under steep slopes is a key task for tunnel engineering disaster prevention and control,and it is crucial to scientifically and reasonably evaluate the construction risks of tunnels.The article takes the Xiali Tunnel of the Jixin Expressway project as an example,introduces the optimal transfer matrix to calculate the weight ranking of the construction risk evaluation indicators affecting the tunnel entrance section.At the same time,combined with mutation theory,the evaluation indicator values are dimensionless processed and normalized according to the weight ranking to obtain the overall mutation level value.By comparing the comprehensive evaluation of the improved AHP mutation theory with the results of field investigations,it was found that the results were basically consistent,verifying the reliability of this method in the risk assessment of tunnel entrance construction.
