Reliability Analysis of High Pressure Buried Pipeline under Landslide

Abstract:

The landslide disaster tends to cause safe hidden trouble to the normal operation of the pipeline and pipeline is likely to take place accident and get failed under the action of a landslide. According to the theory of winkler, in the condition of pipeline landslide, the mechanical model is established and calculated the stress distribution under different landslide scale. According to the calculation result, the dangerous section of pipe is obtained. Based on the pipeline's own strength and pipeline working stress in the landslide, the limit state equation of the pipes is set up by using the third strength theory. Finally according to the distribution of stress and strength, the pipeline reliability index and failure probability are obtained by means of the first order second moment method improved. The achievement of this paper has great value .to the buried gas pipeline risk assessment. Key words: landslides; The third strength theory; The first order second moment method; Reliability index; Failure probability
