北京地下直径线工程位于富水砂卵石地层中，穿越诸多建（构）筑物。通过实际监测结果分析，总结掘进参数与地表沉降之间的规律及隧道周围重要建筑物的变形规律，经与类似工程比较后发现本工程在变形控制上有很大的成效。

Beijing underground diameter project is located in the water-rich sandy gravel formation, which is through many structures .Through the analysis of actual monitoring results,the law of tunneling parameters to surface subsidence and deformation law of important buildings around were summarized. Deformation control was successful compared with similar projects.
