| Abstract: | Guantouling Tunnel of Wenzhou-Fuzhou Railway underpasses Guantouling Tunnel of Tong-San Expressway at DK280 ＋950 - DK281 ＋ 100. The railway tunnel excavation profile＇s roof surface is only 2.9 m under the expressway tunnel＇s infrastructure base, with a plane angle of only 36°. Such a construction condition is the first case ever encountered in china and in the world. Construction planning is based upon the important reference to numerical simulation calculations, and the construction is organized dynamically according to the monitoring measurement results to ensure the railway tunnel construction could pass through the expressway tunnel fast and safely. |
