The invention discloses a rapid judgment method for hydraulic connection among aquifers. Specifically, the method comprises the steps of laying out profile points in a study area according to designedmeasurement lines through adoption of a time shift transient electromagnetic depth measurement technology before a water pumping test is carried out, and measuring a transient electromagnetic signalon each measurement coordinate of a profile, thereby obtaining groundwater distribution electromagnetic response characteristics before groundwater migration condition is changed; laying out a water pumping hole and an observation hole, observing a groundwater level initial value, carrying out the water pumping test in the water pumping hole, and recording water levels in the water pumping hole and the observation hole; carrying out detection through reusing of a time shift transient electromagnetic method, thereby obtaining the groundwater distribution electromagnetic response characteristicsafter the groundwater migration condition is changed; and finally, carrying out difference analysis of the two times of groundwater distribution electromagnetic response characteristics, taking the water levels in the water pumping hole and the observation hole as constraint conditions, correcting a data processing result, establishing a groundwater migration three-dimensional model in the studyarea, and intuitively judging a replenishment relationship among the aquifers.
