Comparison between Combined and Separate Construction Schemes for Tunnel on Chengdu-Lanzhou Railway |
| |
| Abstract: | It fully introduces the selected conditions that Chengdu-Lanzhou Railway is subject to complicated engineering geological conditions, and there applies combined (single-tunnel double-track) and separate (double-tunnel single-track) construction scheme for tunneling. The paper from 5 aspects, project investment, structure adaptability, construction risk, progress, operation and maintenance, made the technical and economic analysis for comparison, which offers selection references for combined and separate construction schemes. |
