| 摘 要： | 以穿越地裂缝带的西安地铁2号线为研究背景,通过数值模拟对地裂缝作用下马蹄形地铁隧道与土体相互作用的机理进行了研究.研究结果表明:随着上、下盘位错量的增加,地裂缝处受影响的土体范围逐渐增大,土体的竖向位移也逐渐变大;上盘下降过程中,下盘隧道顶部沉降变形最大,上盘隧道顶部沉降变形最小;隧道的变形区域出现在预设地裂缝两侧,并...

| Abstract: | The Metro Line 2 in Xi'an running across the ground fissures is taken as a research background, and the interaction between soil and U-shaped metro tunnel is studied by numerical simulation in the environment of ground fissures.The results show that the soil mass area is influenced by ground fissures and the vertical displacement gradually increases with the relative displacement increasing.When the hanging wall descends,the settlement deformation of footwall is maximum,and that of the hanging wall is minim... |
