Based on overlapping tunnel section from Hongshan Square Station to Zhongnan Road Station of Line No.2 and Line No.4 of Wuhan Metro, this paper proposed a principle of "finish the following part first" for subway construction considering the features of overlapping tunnels with short-distance. It mainly elaborated several key measures, such as shield tunneling control, grouting for mezzanine soil, temporary support in tunnels. Then the monitoring results proved the feasibility of the measures, so that this paper can provide reliable experience for the designation of overlapping tunnels and construction management in the following years.
