Paper Title:
The Research of Existing Railway Survey and Evaluation Methods
  Abstract

Based on the contrast of survey method in existing railway, considering the actual situation on site, nuclear densimeter, Evd and light dynamic penetration methods were used in survey, and then analyze influencing factors of survey results in existing railway. Since there is no mathematical statistics method for survey evaluation in existing railway, taking "Quality inspection and evaluation standards for highway engineering" as reference, evaluation standard for existing railway at 200km/h was proposed. Filling materials segment method, task segment method and enforcement segment method were used for the evaluation in Ning-Qi existing railway, the road sections length that need reinforcement was reduced, which achieves good effect.
