Preliminary Research on Risk Pre-warning of Airport Underground Drainage Safety

Airport drainage difficulty not only directly affects the service efficiency of the flying ground and flight safety of the aircraft, and but also jeopardizes the strength of the runway and parking apron. It is of great significance to take safety risk assessment and pre-warning for airport under-drainage. Firstly, it introduces the importance of the airport drainage, designing contents, as well as the function and composition of the airport under-drainage system, which takes necessary foreshadowing for the full text in the paper; then, it summarized generally the domestic status of airport drainage, control of drainage safety risks and domestic and international water level monitors; and on the base of that, it presents a study consideration for fuzzy risk evaluation and control with sensor technology and hydro-geological condition, and assume a simple pre-warning flow for airport under-drain safety risk; finally, it analyzes the cases about safety risk management for construction of under-drainage project without intermission of flight.
