摘要：
Based on a large-scale excavation adjacent to metro line, the design and construction schemes and monitoring data of metro structures during construction are analyzed. Some conclusions are drawn as follows: the movement of metro structures due to the adjacent excavations can be effectively controlled by stage excavation. Considerable rebounding displacement and horizontal displacement orient to the excavations can be induced by excavation unloading. The displacement of metro structures can be effectively controlled by sleeve-valve-pipe grouting, and rectification of metro structures can be executed. The time-space effect is obvious in this kind of projects. © 2017, Editorial Office of Chinese Journal of Geotechnical Engineering. All right reserved.
