AI Technical Summary
Existing methods for identifying the water-soil interface suffer from low accuracy, complex operation, high cost, and inability to achieve dynamic monitoring. This is especially true in marine environments, where sonar detection is affected by water turbidity and air bubbles, remote sensing has low spatial resolution, and borehole sampling is complex to operate and unsuitable for dynamic monitoring.
A method based on linear heat source heat transfer is adopted. An integrated device consisting of a linear heat source and a temperature monitoring unit is vertically deployed in the area to be identified to monitor temperature changes in real time during the heating and cooling process. By utilizing the difference in the unsteady heat transfer behavior of the linear heat source in water and soil, and combining it with an unsteady heat transfer analytical model, the location of the water-soil interface is accurately captured.
It achieves efficient and accurate positioning of the water-soil interface, enables dynamic monitoring of changes in the water-soil interface, simplifies operation, and reduces costs.
