【摘要】 隧道施工时如果遭遇断层破碎带,围岩通常较为破碎,对隧道安全施工造成很大隐患,选择科学、经济、合理的施工方案就显得尤为重要。岭脚隧道受断层破碎带影响,引发涌水、突泥地质灾害。为选取合理的开挖方式,本文通过数值模拟分析,对该隧道受断层破碎带影响区域进行不同开挖方式的模拟,通过对数据进行对比分析,得出适合该隧道的开挖方式。更多还原

【Abstract】 A fault fracture zone causes great hidden trouble for tunnel safety construction when the tunnel is building. The choice of scheme which is Scientific,economic and reasonable is very important. Lingjiao tunnel which is affected by the fault fracture zone,causes water burst and mud inrush. In this paper,for the selection of reasonable excavation method,different excavation methods is analyzed under the fault fracture zone. We determine the tunnel excavation method through the study of the comparison and analysis of the dat.更多还原
