| 摘 要： | 地裂缝在地铁设计使用期内的最大垂直位错量是西安地铁二号线穿越地裂缝结构设计的一个十分重要的参数。本文以历史水准监测资料为基础,分析了西安地铁二号线沿线各地裂缝在不同历史阶段的活动特征与活动原因,对各地裂缝的未来活动趋势进行了预测。然后通过基于不同时间段地裂缝活动速率的最大垂直位错量估算结果的对比分析,得出了地铁设计使用期内各条地裂缝与地铁交汇点处地裂缝的最大垂直位错量,并以此为依据,将西安地铁二号线沿线地裂缝分为Ⅰ、Ⅱ、Ⅲ和Ⅳ级等4个工程级别。

| Abstract: | The maximum vertical displacement of ground fissure is an important parameter to the structural design of Xi’an Metro Line 2 going through ground fissures.Based on leveling monitoring data,the activity characteristics in different stage of each ground fissure along Xi’an metro Line 2 are analysed in this paper.The future activity trend of each ground fissure is predicted.Then through the contrast analysis of the maximum vertical displacements calculated by the annual activity rate of different historical stages,the maximum vertical displacement of crossing points in which ground fissures intersect with Xi’an Metro Line 2 are gotten.The ground fissures along Xi’an Metro Line 2 are classified into four categories,i.e.Ⅰ,Ⅱ,Ⅲ and Ⅳ according to the maximum vertical displacements of ground fissures. |
