Abstract: According to Newmark-Hall method, this paper proceeds the seismic reliability contrastive analysis of buried pipeline crossing fault, mainly based on different pipeline with fault crossing angle and buried depth by using Monte-Carlo method. The analysis result shows: seismic performance is highest when the pipeline with fault crossing angle reaches between 80 degree and 100 degree; the reliability performance will be improved when pipeline buried depth decreases.
