The invention relates to the technical field of building
engineering information, and discloses an
engineering project digital archive management method based on BIM. The method comprises the following steps: initializing a BIM platform environment, importing a BIM model and related archive data, and carrying out
standardization processing; constructing a project component association graph and an archive data flow graph by using a graph technology; and capturing state change through
event monitoring, and synthesizing a project operation
state diagram and an archive data dynamic flow diagram in real time. The core innovation lies in that a row calls a
semantic analyzer and an authority checker to scan and check a double-dynamic graph, and outputs an abnormal identifier set; positioning an abnormal node and performing dependency chain
backtracking along an archive flow graph, and accurately extracting a problem root; a
test case is generated by combining
static analysis and a novel
test strategy, and defect details are monitored and recorded during operation. And integrating the problem root and the defect
record to generate a comprehensive management report. According to the invention, the real-time performance of
engineering file management and the accuracy of problem tracing are improved.
