| Abstract: | Through analysis on No.4 tank project overrun subsidence of Tianjin Branch Company attached to China Oil Limited Corporation,main reasons caused the subsidence of piles foundation are found.By using static pressure grouting treatment method,water physical property between piles has been improved,the friction between piles have been increased.Foundation reinforcement can relieve and eliminate the subsidence problems occurred in existing buildings. |
