Abstract：Based on the comparison and verification of numerical calculations and monitoring results for the Huangzhuang station in Beijing, three-dimensional models of the North Taipingzhuang station were established using FLAC3D to research the influences of four factors, the pipeline buried depth, horizontal position, pipe diameter, and angle between the pipeline and the station, on the surface and pipeline settlement during the construction of a metro station using the pile-beam-arch (PBA) method. A grey model was established based on the numerical simulation results to predict the settlement of the pipelines and the surface for different cases. The results show that the ongoing process of settlement can be divided into three stages: before the crossing, through the crossing, and after the crossing. As the burial depth increases, the settlement of the pipelines increases gradually, while it decreases slightly with increasing horizontal position, pipeline diameter, and angle. The settlement prediction results at different burial depths are consistent with the numerical calculation results, indicating that the gray model has a certain applicability for the prediction of surface and pipeline settlement when an underground metro station is constructed using the PBA method.
