Abstract Based on the analysis of the tunnel TBM construction process and technology, using the three-dimensional geological modeling technology and engineering simulation technology, a construction cycle network simulation model was established, which could achieve the prediction and visual analysis of TBM tunnel construction process. Taking the DXL tunnel project in Tibet as the research object, coupled with the three-dimensional geological model of the DXL tunnel, an optimized analysis of the TBM construction schedule of the DXL tunnel was performed through simulation calculations. The relationship between the completion probability and the construction time was fitted, and the expected completion probability was determined. The construction process was visualized and suggestions to guarantee the construction progress were proposed.
