AI Technical Summary
In existing deep foundation pit projects, there are assembly gaps in the mechanical connection parts of the servo steel support system, which leads to signal aliasing, making it impossible to accurately monitor the deformation of the retaining wall. There is a lack of feature separation methods based on physical priors, making it impossible to extract real information on soil property changes from mixed noise.
By acquiring the mechanical pressure compensation data of the servo support device, determining the design stiffness range based on the device parameters, performing linear feature extraction, filtering the inelastic deviation dataset, generating the soil continuous stiffness function, constructing and solving the force balance equation of the retaining wall, and obtaining the lateral deformation curve of the retaining wall.
It effectively identifies and eliminates low-stiffness backlash signals caused by mechanical backlash in servo data, solving the technical problem of distinguishing between mechanical backlash and soil rheology. It extracts real soil property change information from mixed noise and achieves accurate monitoring of wall deformation.
