Research on safety evaluation of intercity rail construction phase based on the extension theory

Combining with construction problems in safety management,the model evaluates the safety management of intercity rail construction phase.According to Guanhui intercity rail construction projects,the construction status of the project has been evaluated by using the index system and evaluation model,and the result of the evaluation correspond with the actual situation.Theoretical analysis and case study indicate that the new method is applicable to intercity rail construction phase safety evaluation.
