High-grade Highway Infrastructure Security Countermeasures

The article is based on the eastern section of the mainline of Hu Rong national road, It put forward some feasible prevention's technology and measures directing against different type of engineering, which is based on the investigation and analysis to types and formation's cause of various engineering disease of highway's subgrade and pavement, Structure of bridge and culvert and engineering along road. It evaluate the bridge safety by AHP and forecast the character changing with time of bridge structural defect by grey system theories. The achievement provide the foresighting technology prevention and feasible advice about running and mainteance for the east part of the Hu Rong road, also can be used as reference on construction and running management of other building and running highway, and provide scientific basis for relevant technology policy made by responsible department.
