Abstract:
Shield technology was adopted for the construction of the tunnel section connecting the Qiaoxiang, Xiangmi, and North Xiangmei Stations of Lot 2222. Completed on September 10, 2010, this project required overcoming the difficulties of hard rock, rock consisting of a soft upper stratum and hard lower stratum, the under-passing of existing buildings, and passing a mined tunnel during its construction. Focused on the key points of construction risks and quality control, this paper presents the concrete requirements for the two running tunnels in this lot in terms of construction management as well as the results achieved.
