| Abstract: | Rigid pile composite foundation is constructed by sinking cement piling center into the rigid pile, through the reduction of flexible piles with rigid stiffness of pile, the rigid-and-flexible combination with a good mix of soil and a high bearing capacity of pile is formed. Composite foundation of stiffness of pile (C10) has done. Comparing detection, testing and verifying and economy, soft flexible pile replacement rate, less rigid pile composite foundation deformation, and low-cost soft ground treatment ... |
