AI Technical Summary
Existing technologies are insufficient to effectively identify and provide early warning of the coupling state between seabed scouring and liquefaction. They lack unified identification indicators and classification rules, making it difficult to distinguish between single anomalies and coupled anomalies. Furthermore, they fail to utilize pore pressure response and resistivity evolution characteristics in a coordinated manner.
By deploying pore water pressure monitoring units and resistivity monitoring units on the seabed, pore pressure response characteristics and resistivity evolution characteristics are extracted, and judgment functions for scour influence zone and liquefaction enhancement zone are constructed. Scour influence intensity, liquefaction development degree and coupling enhancement index are constructed to achieve state category identification and early warning classification.
It enables rapid identification and early warning of seabed scour-liquefaction coupling, improves the targeting and risk identification capabilities, and outputs more targeted early warning levels, providing a basis for basic risk management at sea.
