摘　　要：针对管道工程可能产生的膨胀土地质灾害问题,探讨了膨胀土的工程特性与地质灾害的关系,膨胀土性质与边坡灾害的关系,以及膨胀土的干燥活化效应与管沟开挖的关系,分析了膨胀土斜坡与边坡地质灾害和膨胀土管沟开挖施工中地质灾害产生的原因,并提出了相应的防治措施和注意事项。In allusion to possible geological hazards induced by expensive soil in pipeline projects,relationships between engineering characteristics of expensive soil and geological hazards,property of expensive soil and side slope,as well as arefaction activation effect are discussed.Reason analysis on geological hazards occurred in expensive soil and/or side slope and ditch excavation in expensive soil areas are carried out,and relative countermeasures and technical issues are brought forward.
