北斗卫星微位移监测系统在油气管道地质灾害监测预警中的应用

油气管道铺设线路所经区域地形条件复杂,受到地质灾害的影响较大,为了避免地质灾害对管道造成破坏,提高油气管道运输的安全性,采用北斗卫星微位移监测模块对管道桩号为JG7410的滑坡地质灾害点进行实时监测。该点处管道穿坡而过,边坡完整性和植被覆盖遭到破坏,存在滑坡风险。我们将监测站布设于管道上方切坡处,基准站布设于距离监测站1km处,监测数据通过基准站进行校正、解算处理后,精度可达毫米级。此外,研究将获取的位移数据与降雨数据进行对比,结果表明:该滑坡体的沉降量与沉降速率主要受降雨因素影响,且沉降速率的加速与汛期有关。这说明北斗微位移监测模块在滑坡位移监测过程中应用前景很好,在很大程度上可以避免重大滑坡事故的发生,保证了油气管道完整性和安全性。

Application of Beidou satellite micro-displacement monitoring system in monitoring and warning of geological hazards in oil and gas pipelines

In order to avoid damage to pipelines caused by geological disasters and improve the transportation safety of oil and gas pipelines, beidou micro-displacement monitoring module is adopted to carry out real-time monitoring on the geological disaster point of the landslide with the pipeline pile number JG7410.At this point, the pipeline passes through the slope, the slope integrity and vegetation coverage are damaged, and there is a risk of landslide. Therefore, the monitoring station is set up at the slope cutting above the pipeline, and the reference station is set up at a distance of 1km from the monitoring station. After the calibration and calculation of the monitoring data by the reference station, the accuracy can reach mm level.In addition, the displacement data are compared with the rainfall data, and the results show that the subsidence amount and the subsidence rate of the landslide are mainly affected by rainfall factors, and the acceleration of the subsidence rate is related to the flood season.This shows that the Beidou micro-displacement monitoring module has a good application prospect in the process of landslide displacement monitoring, which can avoid the occurrence of major landslide accidents to a large extent and ensure the integrity and safety of oil and gas pipelines.
