| 摘 要： | 在对某输气管道线上一个正在活动滑坡变形和管道应变系统监测的基础上，分析了滑坡活动特征及其对管道安全的影响。滑坡监测采用地表位移监测，从而判断滑坡边界、掌握滑坡滑动状态对管道的影响；管道监测采用弦式应变计测其应变，利用强度理论评判管道的安全性。利用监测数据分析管道的轴向稳定性。监测结果表明，在该滑坡区域范围内管道尚属安全，但滑坡仍处于滑动阶段，对管道安全存在隐患。

| Abstract: | In this paper,we did the landslides and pipeline monitoring. Land surface deformation is landslide monitoring to get the landslide deformation information; pipeline monitoring is wire strain gauges monitoring to measure pipeline＇ s strain, using of strength theory to judge the safety of pipelines. Monitoring results show that the landslide in the regional is safe to the pipelines, but the landslide still in the stage of sliding, the hidden danger to the pipeline exists. |
