【Abstract】 ∵ This paper investigates a water pipeline leakage detection method based on an accelerometer.Sensors are arranged at diffrent positions above and around the leakage point of the pipeline to directly collect the acoustic signals from the ground surface and perform spectral analysis to identifyand quantify leakage characteristics. Experiments show that the leakage signal attenuates with increasing propagation distance and experiences a small frequency shift（about 200Hz ）when passing through different ground materials.Different ground materialshave different sound propagation rates for leakage signals （asphalt > concrete pavement，sidewalk slabs > green grassland），and the leakage signal has a greater propagationcapability along the pipeline direction than in directions deviating from the pipeline.This method can effectively capture and analyze leakage signals under complex ground conditions and simplifies the traditional leakage detection process.
