The invention relates to a highway tunnel defect information description and structuralization method based on APP application, and belongs to the technical field of highway tunnel defect detection. The method comprises: S1, system parameters are configured according to highway tunnel structure information; S2, abstracting a tunnel distribution diagram according to system parameters configured bythe tunnel structure information; S3, making different disease type legends according to the tunnel disease types; S4, selecting related legends according to the tunnel site disease positions and disease parameters, and configuring the parameters to describe specific diseases on the tunnel layout; S5, the App application software counts the tunnel disease structured information, and a statisticalresult lists each disease in a structured table; And S6, the App application software automatically generates a tunnel disease information distribution diagram. According to the method and system, frequent inspection and regular inspection work of the highway tunnel are more efficient and intelligent, and the method and system are simple in principle, low in cost and convenient to operate and meetthe intelligent maintenance requirement for guaranteeing safe operation of the highway tunnel.
