Intelligent water conservancy project structure safety monitoring system and monitoring method

The invention discloses an intelligent water conservancy project structure safety monitoring system and monitoring method. According to a provided scheme, the system comprises a top plate arranged at the top of a river levee, two symmetrical vertical holes and two symmetrical transverse holes are formed in the river levee, and the vertical holes are perpendicularly communicated with the adjacent transverse holes; two symmetrical first fixing columns are fixedly connected to the bottom of the top plate, and the stability of the second fixing columns is improved by fixing the second fixing columns to the river levee; the second fixing columns and the first fixing columns are connected, so that a first osmometer, a second osmometer and a first pressure sensor can be used for monitoring at different positions in the river levee, and the stability of the river levee can be enhanced; according to a second pressure sensor, a micro-seismic sensor, the first osmometer, the second osmometer and the first pressure senso
