| 摘 要： | 针对软岩隧道施工中出现的围岩失稳工程难题,结合鄂西某深埋特长隧道的现场地应力测试,通过应用实测数据进行区域应力场回归分析及围岩关键部位变形的数值模拟,综合评价了应力场对该隧道围岩稳定性的影响.结果表明:该隧道测区围岩处于高应力区,且拱顶变形相对较大,围岩稳定性较差.分析结果与现场现象相吻合,说明该方法可行有效,可为隧道施工设计提供参考.

| Abstract: | For the surrounding rock's unstability during the soft rock tunnel excavation,especially in combination with a deep buried and long tunnel in western Hubei Province,the method of regional geo-stress field's regression analysis based on in-situ measured data is employed.The digital simulation of surrounding rock's key displacement field and the comprehensive analysis of stability are both introduced.The result shows that the tunnel's measurement regional rockmass is in high stress field,the displacement of t... |
