基于西南管道地灾排查常见地质灾害辨识分析

Identification and Analysis of Common Geological Hazards on the Strength of Pipeline Disaster Investigation in Southwest China

目前地质灾害频繁发生,主要表现为连续型大降雨、地震等引发的地质灾害,为了减小地质灾害对管道造成的损失,对管道地质灾害的识别显得尤为重要。基于2017年07—08月对西南管道地质灾害的排查结果进行分析,总结出了6种常见的地质灾害类型,分别为滑坡、不稳定斜坡、泥石流、崩塌、水毁、地面塌陷。本文首先介绍了西南管道的布置范围及沿线的自然条件,其次介绍了各种地质灾害的定义、影响因素及产生的条件,最后分析总结了管道地质灾害的识别及防治措施。本文旨在提出管道地质灾害的识别方法,及其进行治理时的注意事项。

Currently,geological disasters occur frequently,mainly due to continuous heavy rainfall and earthquakes.In order to reduce the losses caused by geological disasters to pipelines,the identification of geological disasters in pipelines is particularly important.On the strength of investigating pipeline geological disasters in southwest China from July to August in 2017,this paper summarizes six common types of geological disasters,namely landslides,unstable slopes,debris flow,collapse,water damage and ground subsidence.This paper first introduces the layout of the Southwest Pipeline and the natural conditions along the pipeline,followed by the introduction of the definition of various geological disasters,the influencing factors and the conditions for their production.Finally,the identification and prevention and cure measures of the pipeline geological disasters are analyzed and summarized.The purpose of this paper is to propose a method of identifying geological hazards in pipelines and their precautions when managing them.
