AI Technical Summary

Technical Problem

Existing technologies cannot accurately determine the fixed point adjustment coefficient when calculating asymmetrical loads on water-adjacent foundation pits, leading to unbalanced soil pressure during foundation pit construction, which may cause accidents such as excessive deformation of the retaining structure or overall instability.

Method used

By calculating the difference in axial force and displacement increment between the two foundation pits under unbalanced pressure, and using pressure and distance sensors for data acquisition and short-range communication, the fixed point adjustment coefficient is corrected until the preset requirements are met. The support structure is then adjusted by applying pre-loaded axial force, and the calculation is repeated until stability is achieved.

Benefits of technology

This improves the intuitiveness and accuracy of the fixed-point adjustment coefficient, avoids errors caused by intermediate variables, and ensures the stability and safety of the foundation pit support structure.
