管道沉降监测与应用研究

该文介绍了对高压天然气管道采用直接监测点与间接监测点相结合的沉降监测方法。分析了间接监测点代替直接监测点进行管道监测的可行性;并对直接监测点与附近水准点沉降关系,即管道沉降与地层沉降之间的关系进行了初步的探讨,对过去经验地认为管道在敷设后一年后即达到稳定沉降与地层一起沉降的观点提出了质疑。

Pipeline''''s sedimentation monitoring and its application studying

It is introduced in this article that the touching - pipeline monitoring points are substituted by the no -touching - pipeline to monitor the sedimentation of pipelines. The phenomenon is discovered that no -touching -pipeline points get to the stable situation after 12 months under guound, but it need to be monitered for a long time whether the no - touching - pipeline points and the no - touching - pipeline points will sedimentate in step. The bench marks and the touching - pipeline monitoring points isnt discovered to in - step sedimentate before they are laid 12 months. The pipeline in - step sedimentate with the gouand from Match to September and take palce out - of - step sedimentation in other time. But whether the pertubation is regular need further sutdies to be discovered. In a word, this article is just a preliminary study on monitoring the sedmentation of the pipleline, because the monitoring has been done for 2 years.
