| Abstract: | The paper focuses on introducing the tunneling construction method of the New Wanshansi Tunnel of the Da-Cheng Railway,during the construction of which simple measures,such as strengthening the side and front slopes,slip-casting with small lead tubes,and the method of ring excavation with the core soil reserved,are taken instead of the complex large-tube shed construction scheme.The adoption of these measures helps not only to lower the cost of the project but also to accelerate the construction progress,an... |
