6 FAQs about [Bearing capacity of photovoltaic support piles]

Is a PHC pile foundation a reliable support structure for heliostats?

A comprehensive design program is proposed based on field tests and numerical simulations, considering deformation and bearing capacity. The study confirms the reliability of the PHC pile foundation as a support structure for heliostats, aiming to offer valuable insights for practical applications.

How much lateral load can a pipe pile hold?

Considering that the flexural capacity of pipe pile for design was about 88 kN·m, the lateral load acting on the column should not exceed 30 kN. Therefore, the maximum load was set to be 39 kN, loaded in 13 grades (i.e. each grade of load was 3 kN higher than the preceding grade).

Does the bearing capacity of a cantilever column influence the design?

The deformation and residual deformation of the pile in sand layer site were obviously larger, and the column could not be loaded further until the column cracked under 12th load grade, which indicated that the bearing capacity of the cantilever column might play a controlling role in the design.

How does torsional load affect PHC short pile foundation deformation?

The deformation of PHC short pile foundations exhibited distinct phases. Torsional load reduced the column crack load by 30%. The pile cap effectively controlled plastic deformation, minimizing foundation deformation, while torsional load increased lateral deformation.

Does lateral load affect the deformation resistance of pile cap?

Compared with the lateral load condition, the deformation of the foundation increased and the crack load reduced by about 25%. This indicated that the deformation resistance of pile cap under combined load was significantly improved, but the torque greatly weakened the ultimate failure load.

Does pile cap thickness affect torque distribution in a PHC Foundation?

Color contours of the PHC foundations with different pile cap sizes (foundation length: 3.5 m) In conclusion, pile cap thickness played a crucial role in torque reduction, and pile cap side length significantly influenced internal force distribution within the PHC short pile foundation.
