岩溶区公路隧道修筑风险评估方法及应用

Risk Assessment Method and Application of Highway Tunnel Construction in Karst Area

文章结合工程实例采用地质经验法与目标分解方法、成分分析法相结合的方法,建立岩溶区公路隧道修筑风险评估指标体系,以层次分析法确定相应指标的权重,从定性的地质分析转向定量的数学模型计算,将各风险因素定量化,并确定其权重与主控风险因素,进行风险度计算和评定风险等级。

Combined with engineering examples, this article established the risk assessment index sys- tem of highway tunnel construction in karst area by combining the geological experience method,tar- get decomposition method and component analysis method.The weights of corresponding indexes were determined by analytic hierarchy process（AHP）, from qualitative geological analysis to quantita- tive mathematical model calculation, all risk factors were quantified, and then it determined its weight and main control risk factors, and conducted the risk degree calculation and risk level assessment.
