Tunnel hydrogeological survey method and device, computer equipment and storage medium

The invention provides a tunnel hydrogeological survey method and device, computer equipment and a storage medium, and relates to the technical field of tunnel construction surveying.The tunnel hydrogeological survey method comprises the steps that a lower packer and an upper packer are sequentially arranged in a drill hole, a target aquifer is sealed through the expanded lower packer and the expanded upper packer, and the target aquifer is sealed through the lower packer and the upper packer; rapid pressure relief is achieved by sucking the target aquifer so that a negative pressure state can be formed in the target aquifer, the underground water seepage process can be conveniently and rapidly simulated, the recovery water pressure of the target aquifer in each time period can be detected and recorded, and the most reliable water pressure data outside the tunnel can be obtained; according to the device, reliable and accurate data support can be provided for tunnel hydrogeological survey, simulation testing c
