完整性管理马显春等：堆载体诱发滑坡与管道相互作用的风险防控方法*油气田地面工程https://yqtd.cbpt.cnki.net堆载体诱发滑坡与油气管道相互作用的风险防控方法研究*马显春1黄谱2乔坤3田波2魏楠2聂军2梁永龙21中铁西南科学研究院有限公司2中国石油西南油气田分公司川中油气矿3青海油田监督监理公司摘要：随着人类工程活动日益强烈，堆载体诱发的滑坡逐渐增多。为降低堆载体诱发滑坡对油气管道建设及安全运营的危害，亟待研究其发育机制及风险防控方法。通过资料搜集、现场调查、室内试验、物理模拟及理论分析，归纳总结了油气管道区堆载体特点及其诱发滑坡的发育阶段，提出了堆载体诱发滑坡与油气管道的相互作用机制及其风险防控方法。结果表明：堆载体诱发滑坡的发育阶段与油气管道变形具有对应关系，即在沉降压密阶段油气管道为弹性变形，从蠕变挤压阶段开始管道进入塑性变形；堆载体诱发滑坡的防控应采用尽早、尽小的原则。关键词：油气管道；堆载体；滑坡；作用机制；风险防控StudyonRiskPreventionandControlMethodsofLandslidesInducedbySurchargeLoadsandTheirInteractionwithOilandGasPipelinesMAXianchun1，HUANGPu2，QIAOKun3，TIANBo2，WEINan2，NIEJun2，LIANGYonglong21ChinaRailwaySouthwestResearchInstituteCo.，Ltd.2ChuanzhongOilandGasMineofSouthwestOilandGasFieldBranch，CNPC3QinghaiOilfieldSupervisionCompanyAbstract：Withtheincreasingintensityofhumanengineeringactivities，landslidesinducedbysur-chargeloadareincreasingdaybyday.Inordertoreducethehazardsoflandslidesinducedbysurchargeloadtopipelineconstructionandsafeoperation，itisurgenttostudytheirdevelopmentmechanismandriskpreventionandcontrolmethods.Throughdatacollection，fieldinvestigation，laboratorytest，physicalsimulation，andtheoreticalanalysis，thecharacteristicsofthesurchargeloadsintheoilandgaspipelineareaandthedevelopmentstageoflandslideinducedbythemaresummarized，theinteractionmechanismbetweenlandslidesinducedbysurchargeloadsandtheoilandgaspipelineandtheriskpre-ventionandcontrolmethodsareputforward.Theresultsshowthatthereisacorrespondingrelationshipbetweenthedevelopmentstageoflandslidesinducedbysurchargeloadsandthedeformationofoilandgaspipeline.Inthestageofsettlementandcompaction，...
