Building of Technology System of Pipeline Geohazard Monitoring Based on Its Characteristics
For the particularity of the harming object, the pipeline geohazards have their own characteristics; so, the monitoring methods for pipeline geohazards should also reflect their characteristics. Based on the investigation of geohazards along the Zhongxian-Wuhan natural gas pipeline and Sichuan-East natural gas pipelines, the volume distribution characteristics of landslides and unstable rocks along the pipelines were analyzed. A new scale classification is put forward in which landslides and unstable rocks are divided into four grades: small, medium, large and extra-large grade, respectively. The corresponding classification level indicator is 1/20 of the conventional landslides and 1/100 of the unstable rocks. This classification highlights the importance of small-scale geohazards along pipeline. According to the volume classification and combining with the risk rank of pipeline geohazards, a technical and method framework is put forward for pipeline geohazard monitoring. It reflects that no monitoring or only manual inspection is arranged for the small-scale, low-risk pipeline geohazards, while integrated monitoring, from ground surface to underground, from deformation to multiple fields, from disaster body to pipeline body, is considered to the large-scale, high-risk cases. This framework is beneficial for determining monitoring investment for pipeline manager, and choosing monitoring contents and methods for engineer.
