摘要
利用Midas-GTS大型有限元软件,对西安地铁区间结构小角度穿越地裂缝特性进行数值模拟,得出地铁区间结构随地裂缝沉降变化的规律,并在此基础上对区间结构穿越地裂缝区段设防方式进行了研究,所得结论对区间结构小角度穿越地裂缝的设计及施工有一定的参考价值。
By using Midas-GTS, the paper makes a numerical simulation of the characteristics of Xi' an metro' s interval structure crossing ground fissures from a small angle, and obtains the pattern of the metro' s interval structure with the sendimentation of ground fissures. Based on this, it also studies the defense method when the interval structure crosses ground fissures. The conclusion will be of some value for the design and construction of the interval structure crossing ground fissures from a small angle.
