| Abstract: | Few researches on tunnel deformation and cracking is available in China. In this paper, we introduced the settlement of metro tunnels in a certain area. By analyzing the causes, we pointed out that the foundation pit excavation and dewatering adjacent tunnel were the two main causes of settlement. Based on the safety evaluation, we provided the repair methods. |
