| Abstract: | The 3D-finite element numerical simulation was adopted, and bearing mechanism, loading transfer behavior and varying law of stress and displacement field of squeezed branch pile are reproduced successfully based on results of static loading test. Optimal spacing of disks and piles are pointed out according to the varying bound of stress and displacement field, and an important basis of quantization are provided for optimazing design and construction of squeezed branch pile. |
