[0001] The present invention relates to the technical field of data processing, and in particular to a method and system for planning a construction path of underground pipeline area pile groups based on BIM. Background Art

[0002] Shield construction is generally carried out underground. Due to the existence of very complex pipelines and pile foundations during the construction process, the construction difficulty and risk are high, which places high demands on the planning level of the construction route.
