| Abstract: | According to the geology conditions of shield construction section in Guangzhou-Foshan Intercity Rail Transit, the earth pressure balance shield machine is adopted for construction. A certain technical measures must be used in construction to avoid the problems of ground settlement, tunnel spewing, and difficult control of shield posture appeared in water-rich sand layer operation by shield machine. The technical points, such as technological process, operation points and mixture ratio of key materials, are... |
