摘　　要：中缅天然气管道贵州段滑坡灾害的发育受到岩土体类型和特征、斜坡结构类型与特征、降雨与人类工程活动等诸多因素的影响。针对管道沿线发育的滑坡特点和管道变形特点,总结出滑坡变形监测技术和管道应力应变监测技术,计算出管道应力监测预警阀值和总结出滑坡位移-管道安全监测预警阀值。以中缅天然气管道蒋坝营滑坡为例,提出了一套较完善的管道滑坡的在线监测预警方案,实现对预警进行分类和预警生成。将滑坡变形监测技术和管道应变监测技术有机融合,能较好地预测滑坡的变形趋势和管道的安全性,为其他管道地质灾害监测预警技术提供参考。The development of landslide hazards in Guizhou section of China-Myanmar natural gas pipeline is influenced by many factors,such as types and characteristics of rock and soil mass,types and characteristics of slope structure,rainfall and human engineering activities.According to the characteristics of landslide and pipeline deformation developed along the pipeline,the technology of landslide deformation monitoring and pipeline stress and strain monitoring are summarized,and the early warning threshold of pipeline stress monitoring and landslide displacement-pipeline safety monitoring are calculated.Taking Jiangba Ying landslide of China-Myanmar natural gas pipeline as an example,a complete online monitoring and early warning scheme of pipeline landslide is proposed to realize the classification and generation of early warning.The organic integration of landslide deformation monitoring technology and pipeline strain monitoring technology can better predict the landslide deformation trend and pipeline safety,and provide reference for other pipeline geological disaster monitoring and early warning technology.
