The invention relates to the technical field of digital twinning, in particular to a
pile foundation construction whole process digital twinning
system which comprises a twinning configuration module, a
dynamic mapping module, a
coupling analysis module and a twinning synchronization module. According to the method, a time axis driving model sequence is constructed based on space-time interpolation, burial depth coordinates, pouring time and segment numbers are dynamically bound, three-dimensional evolution mapping of a
pile body model is achieved, axis coordinate deviation is combined with perpendicularity threshold extraction,
virtual model coordinates are corrected in real time through
point cloud registration, and a
pump pressure value and settlement are fused to generate a
pile sinking rate index. A
bidirectional coupling relation between parameters and stratum response is established in combination with stratum counter-force and
injection rate, the thickness of the model is adjusted according to a settlement
rate difference value, the similarity of the
injection rate and a counter-force curve is matched, a
model parameter reverse updating mechanism is formed, and real-time intervention of construction abnormity, dynamic optimization of parameter
coupling and model iteration correction are achieved. And the process
controllability and the quality tracing precision are improved.
