| Abstract: | The equivalent axial rigidity of single pile in friction pile group is proposed. The determing method of the equivalent axial rigidity is given by using measured-in-situ data. The application scope of the absolutely rigid cap in the design of bridge pile foundation is analyzed with the new concept. The difference of the loading mechanisms between friction pile group and rock-socketed pile group is also discussed. |
