土栖白蚁危害机理与智能监测探讨OA

Subterranean termites,represented by Odontotermes formosanus,Macrotermes barneyi,and Odontotermes hainanensis,constitute the primary biological hazard to embankment dams in water projects.Through hundreds of millions of years of evolution,their eusocial structure,extraordinary reproductive capacity,and extreme concealment enable them to build extensive underground nest colonies and tunnel networks after invading embankment dams,severely damaging soil structures,inducing seepage and piping,and directly threatening engineering safety.Restricted by delayed detection,difficult eradication,high environmental risks,and frequent recurrence,traditional prevention and control methods fail to address the concealed damage posed by the subterranean termites.This paper systematically elaborated on the core biological characteristics and damage mechanisms of subterranean termites,with a focus on introducing the intelligent subterranean termite monitoring system for water projects developed to tackle the aforementioned bottlenecks.Supported by key technologies including specially formulated composite baits with an effective attraction radius of over 7.5 meters and a 100%feeding rate,multi-sensor fusion,and AI intelligent recognition boasting an identification accuracy above 99.95%and a false alarm rate below 1.5%,the system realized early monitoring,accurate identification,and real-time alarming of termite activities.Application results show that this system can significantly reduce the termite damage recurrence rate and engineering repair costs.In the future,termite prevention and control in water projects should continue to advance toward the goals of being intelligent,green and integrated.
