It is very important to study the influences of different construction methods on adjacent existing metro station and propose feasible control measures. Hence, the risk control measures for newlybuilt station foundation pit on Nanjing Metro Line No. 5 closely crossing underneath adjacent station on Line No. 2 are studied. The conclusions are drawn as follows: (1) The existing metro station is divided into 2 foundation pits by separation pile, which can guarantee the normal operation and structural safety of the existing metro station. (2) Tenstepped heading excavation method and zerocovered support system are used for mined section of transfer node, which can effectively control the sinking of the existing metro station to guarantee its safety.
