| 摘 要： | 金子山隧道是宜万铁路8座长大一级风险隧道之一,隧址地形、地貌复杂,地质条件多变,施工中不良地质灾害频发,施工难度很大。以金子山隧道穿越F2岩溶富水破碎带施工为工程背景,详细介绍了隧道穿越该断层破碎带的施工方案。为合理评价隧道的稳定性,在现场监测基础上提出了基于承载体变位分析的位移量(率)评价标准,将这一标准运用到金子山隧道穿越岩溶富水破碎带的施工监测中,取得了较好的效果。

| Abstract: | Jinzishan Tunnel is one of the eight first-grade dangerous great tunnels in Yi-Wan Railway.Because topographical,geomorphic and geological conditions are complicated and changeable,the geological hazards happen frequently during the construction.Taking Jinzishan Tunnel passing through F2 fractured karst area rich in water as background,the construction scheme for the tunnels passing through the fractured fault karst zone is introduced in detail.In order to give a rational evaluation on the stability of the ... |
