结合北京地铁十四号线穿越既有建筑物的实例,进行了现场调查、分析,利用有限元软件模拟计算,得出了建筑物发生破坏时的允许变形量,为该区间施工组织设计提供了依据。%Combining with the example of Beijing subway line fourteen cross the existing buildings, this paper made spot investigation, used the finite element software simulation and calculation, gained the allowing variables of buildings were destroyed, provided basis for interval construction and organization design.
