Abstract

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.
