| Abstract: | This paper is based on the background of Pile - Beam - Arch method applied in the engineering practice of the North Gongti Road Station of Beijing Metro line 10, it introduces the advantages of PBA method in full, makes a study on some technology details such as construction of edge arch, backpacking of pilot tunnels, construction of the first main arch lining, excavation of soil mass between pilot tunnels, construction of platform slab, construction of the second main arch lining and generalizes the technological key points of PBA method. It also illustrates the key points of admeasurement and quality control, which can serve as a reference for other similar engineering practices. |
