| Abstract: | The foundation of 39~# main tower pile of bridge over Liaohe River is one of pile group with large diameter,in deep water and overlong.After grouting the foots of all 39 piles is carried out,effectively enhancing the bearing capacity of pile foundation and its integral rigidity and reducing the inhomogeneous settlement of foundation.The paper emphatically introduces that large-scale pile group foundation lifts mechanism of bearing capacy through pile foot grouting;grouting technology and effects. |
