Non-metal water supply pipeline leakage position positioning method considering soil body influence

The invention discloses a non-metal water supply pipeline leakage position positioning method considering the influence of a soil body. The method comprises the following steps: constructing a wavenumber prediction model # imgabs0 #; a first exposed measuring point is selected in a non-leakage pipe network range, and a first vibration sensor is arranged; acquiring a first vibration signal, and processing the first vibration signal to obtain an actually measured complex wave number; buried soil body parameters of the simulation pipe section are calculated according to the actually measured complex wave number; inputting the frequency of each target sound wave and the parameters of the buried soil body into a wave number prediction model to obtain the comprehensive wave number of each target sound wave, calculating the sound wave speed of a full frequency band, and drawing a frequency division speed curve; selecting a second exposed measuring point at the suspected leakage target pipe section, and arranging a s
