公路地质灾害的灾前识别方法研究

为了减轻地质灾害对公路交通的危害,灾害的超前识别显得尤为重要。通过总结分析已有研究成果,提出了公路地质灾害灾前识别的目的和原则;运用现场调查和理论分析方法,从孕灾环境、灾变迹象、设计施工影响等方面,研究了崩塌、滑坡类公路地质灾害的易发路段及其识别方法,提出了识别判据(其中崩塌灾害的识别判据8条,滑坡类灾害识别判据9条),使潜在崩塌、滑坡地质灾害的识别成为可能,可以为公路地质灾害的预防和治理提供参考,使公路地质灾害治理更加主动和超前。通过工程实例应用,表明该文的灾前识别方法具有较好的可操作性和实用性。

A Study on Pre-disaster Identification for Highway Geological Hazard

In order to prevent and mitigate geological hazards,the pre-disaster identification is becoming very important for highway engineering and transportation.The purposes and principles of pre-disaster identification for geological hazard of highway are proposed through analyzing and summarizing researching results.According to hazard environment,design and construction and signs of deformation,the prone sites and the pre-disaster identification methods for collapse and landslides of highway geological hazards ...
