摘要
应用强度折减法,采用隧道特征点位移发生突变作为隧道失稳的判据,进行两相邻隧道的相互影响的数值模拟计算分析。以其中一座隧道埋深50 m,直径6.6 m保持位置不变(称为既定隧道),另一座相邻隧道在既定隧道的正上方、右上方、右并行、右下方、正下方、左下方、左并行、左上方共8个方位分不同净距采用FLAC~(3D)有限差分软件进行建模计算,最终得出隧道安全系数随埋深的变化曲线以及两相邻隧道的安全系数等值线。研究结果表明:在深埋情况下,两相邻隧道在水平方向上近接的相互影响程度比其他方向上的相互影响程度都大;根据两相邻隧道安全系数等值线以及隧道安全系数随埋深的变化曲线划分出两相邻隧道的强影响区、弱影响区、无影响区等三个影响分区。
Abstrac The author had modeled with FLAC to analysis the interaction of adjacent tunneling based on the Strength Reduction Method,witch is base on the themutationof the tunnel displacement.One of the tunnels stayed the same location is buried depth 50 m and its diameter is 6.6 m,witch is named established tunnel.The other tunnel is located at the eight kinds of directions of the established tunnel.Setting up the stratum structure model in some kinds of excavation conditions to analyze.Finally the isopleth of safety factor of tunnels and the safety coefficient curve with depth aredrew.The results show that the interaction of adjacent tunnel witch are deeply buried based in a horizontal direction is stronger than in other directions;Based on the isopleth of safety factor of tunnels and the safety coefficient curve with depth,three interaction zones of the adjacent tunnel are made out included the strong-interaction zone,the weekinteraction zone and no-interaction zone.
