Abstract: The stability of the intermediate column is the key of cutandcover construction of superdeep Metro station. The monitoring of the settlement of the intermediate column plays a very important role in the safe construction of the Metro station. Remote and automatic monitoring is made, by means of hydrostatic leveling technology, on the settlement of the intermediate column of the superdeep foundation pit constructed by cutandcover method. The monitoring data and the construction safety are analyzed. Suggestion is made on the control standard of the intermediate column. Continuous monitoring of the intermediate column is realized.

Key words: transportation hub, superdeep foundation pit, intermediate column, hydrostatic leveling, remote and realtime monitoring
