This invention belongs to the technical field of computer-aided design and simulation, and relates to a method and system for calculating the leakage of hydraulic facilities by integrating multi-source data. The method includes: receiving raw sensor time-series signals and reconstructing a multi-dimensional time evolution trajectory in a local phase space; extracting the dynamic deviation at abrupt changes and encoding it as a hydraulic transient characteristic tensor; performing singular value decomposition on the tensor using a discrete fractured mesh model to extract the feature spectrum; when it matches the critical deformation matrix, activating the nonlinear turbulence equation to rewrite the state parameters and outputting the pressure head distribution; calculating the simulated entropy yield based on the flow field gradient characteristics and thermodynamic laws; if it is less than a compliance threshold, generating a channel mask array to shield abnormal data sources; if the threshold is met, calculating the facility leakage. This invention solves the problem that insufficient fusion depth between the physical model and multi-source monitoring data leads to limitations in the reliability and real-time response of leakage calculation under complex operating conditions.
