Abstract:
The formwork installation and concrete casting for the arch lining construction of Qingniandajie station on line 1 of Shenyang Metro, which is a mined threespan station constructed by PBA method, is presented in the paper. At the same time, the sucessful construction experience in the waterproofing of the joint between the arch lining and the side wall are presented. Finally, the characteristics of the ground surface settlement occurring during the arch lining construction of the multispan Metro station are analyzed on basis of the simulation made before construction and the realtime monitoring data. The analysis results show that the installation of the arch lining is one of the key procedures of PBA method.
