摘要以西安地铁三号线工程为研究背景，运用物理模拟及数值模拟对隧道近距离平行通过活动地裂缝开展试验研究。对地铁隧道在净距30 m条件下平行通过地裂缝的工况进行物理模型试验，对净距5～50 m的6组工况进行数值模拟。从位移、受力及宏观变形等方面对隧道结构及岩土体变形破坏特征进行分析，揭示平行条件下地裂缝活动对隧道的影响机制。综合物理模拟与数值模拟试验结果认为，地铁隧道于上盘距地裂缝30 m平行通过活动地裂缝是安全可行的，并提出地铁隧道近距离平行通过地裂缝的安全避让距离。

Abstract：Model test and numerical simulation were applied to study the metro tunnel parallel to ground fissure in short distance based on Xian metro line 3. The condition of 30 m between tunnel and ground fissure was utilized in model test. Numerical calculations about six groups of working conditions were carried out in distance of 5–50 m. Based on displacement，stress distribution and macroscopic deformation，destruction characteristics of tunnel and soil mass were analyzed in detail. The influencing mechanism of metro tunnel parallel to an active ground fissure was revealed. Combined the results of physical model test with numerical simulation，the condition of metro tunnel through in hanging wall parallel to ground fissure by 30 m is feasible and safety. Moreover，the safety distance between parallel metro tunnel and ground fissure was proposed.

Key words： tunnelling engineering ground fissure metro tunnel parallel in short distance model test numerical simulation
