摘要        根据对地裂缝活动的监测数据资料，分析了西安地铁三号线沿线地裂缝活动特征。基于各条地裂缝与地铁三号线斜交的夹角θ、地裂缝倾角β以及各条地裂缝最大垂直位错量H，计算确定了地铁三号线穿越各条地裂缝地段的结构设计预留位移量包括最大垂直位移、最大水平位移和最大轴向位移。同时，通过地裂缝影响带宽度和隧道与地裂缝的夹角θ，获取了地铁隧道穿越地裂缝带的结构纵向设防长度。研究结果可为西安地铁三号线及未来其他线路的隧道穿越地裂缝带的结构设计提供参考。

Abstract： Asing Monitoring data, the characteristics of ground fissures intersecting the Xi'an Metro Line3 were analyzed. Based on the maximum vertical dislocation and the dip angle of the ground fissure, as well as the intersecting angle between the ground fissure and the metro line, the predicted and suggested anti-crack design and reserved displacements (including the maximum horizontal, transverse, and axial displacements) were calculated. Meanwhile, the longitudinal structural treatment length of the metro tunnel that passes through the active ground fissure zone was determined with the breadth of the influential zone of the active ground fissure and the intersecting angles between the metro tunnel and active ground fissure.
