Study On Landslide Stability And Treatment Monitoring Of Jiange Section Of Lan Chengyu Oil Pipeline

Pipeline transportation is one of the most important methods in the transportation of petroleum and natural gas.It is of great economic value,environmental protection value and safety value to ensure the safe and stable operation of the pipeline.Landslides and other natural disasters have seriously affected the safe operation of pipelines in some areas.According to estimates,the Lanzhou Chengdu Chongqing pipeline of Jiange section of line direct threat for slope landslide has been changed line about 170m,the direct economic losses of about 4 million yuan,the potential economic losses of about 20 million yuan.Landslides not only cause serious economic losses,but also pollute the environment and endanger the personal safety of the surrounding residents.It is imperative to control the pipeline in landslide section.The main contents of this paper are as follows.First of all,a detailed survey and analysis of the environment of the landslide in the Jiange section is carried out.Then,the stability of the landslide in Jiange section is calculated,and the condition of under stable condition is obtained.Secondly,this paper evaluates the stability of the landslide in Jiange section,and evaluates the state under different conditions according to the calculation results,and gets the detailed calculation results.Combined with the stability evaluation and calculation,the effective measures for landslide control in Jiange section are put forward,and their applicability is evaluated.Finally,through calculation and reference to relevant data specifications,a scheme for detecting landslide in Jiange section is put forward.By means of theoretical analysis and numerical calculation,this paper not only completes the stability analysis of the landslide section,but also puts forward some effective measures for preventing and controlling the landslide.Moreover,a set of effective landslide evaluation system has been formed.
