Anti-seismic and inclination prevention construction method and structure of building pile foundation of soft soil foundation of coastal area
The invention discloses an anti-seismic and inclination prevention construction method of a building pile foundation of a soft soil foundation of a coastal area. The anti-seismic and inclination prevention construction method comprises the following steps of step 1, enabling the high-plasticity flow soil which is located on the upper portion of a soft soil layer to be solidified into a water and soil solidification layer below the bottom elevation of every bearing platform and piling pipe piles and step 2, arranging the plurality of water and soil solidification layers below the plurality of bearing platforms respectively and forming a composite foundation by the water and soil solidification layers and the plurality of pipe piles together, wherein the pipe piles are arranged below every bearing platform. The invention also discloses an anti-seismic and inclination prevention structure of the building pile foundation. According to the anti-seismic and inclination prevention construction method of the building pile foundation of the soft soil foundation of the coastal area, the constraint of the water and soil solidification layers on the positive friction force and the horizontal force is obtained by the pipe piles in the piling process due to the water and soil solidification layers so as to prevent the pipe piles from being inclined in the process of piling or pile foundation bearing platform soil excavation and the composite foundation is high in horizontal thrust resistance and accordingly the stress working conditions of a single pile foundation are changed, a forming natural foundation is combined into an integral stress system, the stiffness is large, the effective pile length of the pipe piles is shortened, the seismic resistance of the pile foundation is improved, and the bearing capacity is large.
