Compared with the ordinary railway's construction safety management, the track construction on running railway line of PDL has its own characteristics. This essay starts from the analysis of these characteristics, next identify risk of track construction on running railway line of high speed railway for PDL, then establish the hierarchy analysis model, and use the analytic hierarchy process (AHP) for risk assessment.
