The invention discloses an ultra-deep foundation pit
supporting system selecting and monitoring method based on the digital technology, and belongs to the technical field of
building construction.By inputting the specification, the geological condition, the hydrological condition and the load condition of a foundation pit into a foundation pit
supporting system, a
supporting system result meeting the specification is calculated and output; a complete three-dimensional foundation pit supporting
system model is rapidly created in combination with
Dynamo and Revit, a supporting structure construction drawing is output, and a material
list and a calculation report of a supporting structure are generated; then, construction is conducted; the foundation pit supporting
system model is imported into the monitoring platform,
monitoring data of the foundation pit supporting
system are obtained and mapped into the foundation pit supporting
system model, and the current foundation pit supporting deformation condition can be visually analyzed; a data resource
library is established in the monitoring platform, the
monitoring data is compared with the data resource
library, and the future foundation pit deformation condition is predicted; and the monitoring platform is connected with an
alarm device, and when the
monitoring data reaches a threshold value or the predicted deformation condition reaches the threshold value, the
alarm device starts to report early warning information.
