通过数值计算方法对北京地下直径线侧穿地铁2号线某车站的结构变形进行预测，并将预测值与实测值进行对比和差异性原因分析，以期对类似工程预测变形、指定控制指标有一定指导作用。

Deformation forecast is proceeded for the structure of Beijing underground diameter side penetrating one station of metro line 2 by numerical value analysis. The comparative analysis and reasons of difference analysis is proceeded too between predicted value and measured value. Deformation prediction results have certain guiding role for engineering construction alike.
