隧道穿越活动断裂带风险评价研究及工程应用

Risk Evaluation of the Tunnel Passing through Active Fault Zone and Engineering Application

隧道穿越活动断裂带往往造成隧道塌方、结构失稳等风险,文章通过对公路隧道穿越活动断裂带的风险因素进行分析,确定了各个风险因素的权值,采用属性测度分析理论对隧道塌方、结构失稳风险事件进行了分析,建立隧道穿越活动断裂带风险评价模型。实际工程应用效果表明,该评价模型能够对隧道风险评估进行定量分析,可为类似工程提供一种新的方法和途径。

Construction of the tunnel passing through active fault zone often causes collapse and structure instabil⁃ity.The weight of each risk factor is determined by analyzing the risk factors of the highway tunnel passing through active fault zone,tunnel collapse and structure instability are analyzed by using attribute measure theory,and a risk evaluation model of the tunnel passing through active fault zone is established.The practical engineering application effect indicates the evaluation model can analyzes the tunnel risks quantitatively and provide a new method and ap⁃proach for the similar projects.
