Abstract

The K7 + 914 － K7 + 984 segment of deep foundation pit in the Purui Tunnel is adjacent to the 12-layerbuilding，in order to determine the design and construction safety of deep foundation pit，the structure of pile-anchorsupport was used． The 5. 3 calculation software was adopted for the calculation of foundation pit structure，at the sametime the Midas numerical calculation software was also used to simulate excavation of the foundation pit ，the datashows that the foundation pit is safe． It was checked the anti floating computation of the main structure of foundationpit ，the floating resistance value can meet the standard requirements without the need for anti floating design offoundation pit．
- deep foundation pit,
- pile-anchor support,
- numerical calculation software,
- safety,
