摘要
找寻公路隧道口部滑塌影响因素的潜在结构和关键特征是解决口部滑塌的根本性问题。利用系统工程的解释结构模型方法梳理得到隧道口部滑塌风险的11个影响因素,确定各个影响因素之间的关联特性,推理计算口部滑塌风险影响因素的可达特性,并通过构建层次结构模型来解释影响因素之间的支持依赖关系,最终归纳出地下(表)水、地质灾害、爆破扰动和地质勘测为引发公路隧道口部滑塌的关键特征,可为滑塌分析、评价和预防提供科学依据。
The fundamental part of dealing with the landslide at the entrance is to find the potential structure and key factors affecting the landslide at the highway tunnel entrance.This paper applies Interpretation Structure Model(ISM)in System Engineering to obtain11main influencing factors of the landslide risk.First,the paper determines the correlation and reasons the accessibility between the influencing factors.Then,the paper constructs the hierarchical model to explain the support dependency between the influencing factors.Finally,the paper concludes that groundwater and surface water,geological hazards,blasting disturbances and geological survey are the key influencing factors of landslide at the highway tunnel entrance.The results provide the scientific basis for the analysis,evaluation and prevention of the landslide.
