摘要
温（州）福（州）铁路瑭头岭隧道在DK280＋950-DK281＋100下穿同三高速公路王官头岭隧道，铁路隧道开挖轮廓线拱项距公路隧道基础底面仅约2．9m，平面夹角仅为36°，施工工况在国内外尚属首例。施工方案以数值模拟计算为重要参考，根据监控量测结果动态组织施工，确保铁路隧道快速、安全地通过公路隧道。
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.
