摘要
滑坡类灾害是管道沿线主要面对的灾害类型,对管道自身可能造成挤压或者露管的危害,依托广西洛阳镇滑坡监测项目,采用GNSS技术、降雨量计、土压力计等监测该滑坡的地表位移、降雨量、土压力和管道压力等,根据对监测结果的分析,与现场的勘察结果进行对比发现,该滑坡的易发性为中,管道的易损性较低.可以通过在滑坡底部的冲沟位置修建排水沟以减轻降雨对该滑坡的影响,从而减轻该滑坡滑移对管道产生的威胁.通过针对管道沿线地质灾害的监测项目的实践,以期为后续管道相同类型的灾害监测和防护提供一定的理论依据.
Abstract
Landslide-type disaster is the main type of disaster faced along the pipeline,which may cause the hazard of extrusion or pipe exposure to the pipeline itself.This paper relies on the landslide monitoring project in Luoyang Town,Guangxi,and uses GNSS technology,rainfall meter,earth pressure technology to monitor the surface displacement,rainfall,earth pressure and pipeline pressure of this landslide,etc.According to the analysis of the monitoring results,and the comparison with the investigation results of the site,it is found that the landslide's susceptibility is medium and the susceptibility of the pipeline is low.Drainage ditches can be constructed at the location of the washout at the bottom of the landslide to reduce the impact of rainfall on the landslide,thus reducing the threat to the pipeline caused by the slippage of the landslide.Through this paper for the pipeline along the geological disaster monitoring program practice,in order to follow-up pipeline the same type of disaster monitoring and protection to provide a certain theoretical basis.
