AI Technical Summary

⚠Technical Problem

Existing technologies are insufficient to simulate the entire process of a sudden surge of confined aquifers during underground engineering construction, and existing monitoring methods can disturb the strata, failing to accurately reflect the patterns and mechanisms of the disaster.

⚗Method used

A simulation test device for the entire process of sudden surge of a water-impermeable layer-confined aquifer was designed. The device uses a box composed of transparent glass and stainless steel, with a clay water-impermeable layer and a confined aquifer inside. The water pressure is controlled by a constant pressure water supply component, and the thickness of the water layer and the permeable holes are adjusted by a permeable filter sand plate. Undisturbed monitoring components such as soil pressure cells, water pressure cells, displacement monitors and DIC cameras are set up for real-time monitoring.

🎯Benefits of technology

It realizes the full-process simulation and multi-source undisturbed monitoring of confined aquifer inrush, can adjust the inrush crack width and water volume, collect real formation physical parameters, avoid sensor disturbance to the formation, and provide accurate analysis of disaster patterns and mechanisms.
