| Abstract: | The following protection measures are taken for subway line 5 in the process of foundation pit excavation.Underpinning beam is used on the top of the tunnel;excavate in sections and return the press by different sections when water level recovers;prepare the press before the water level recovers.And finally the unload way is adopted by laying.These measures keep subway line 5 in normal operation. |
| Keywords: | foundation pit excavation subway beam underpinning |
