6 FAQs about [Analysis of prestressed piles for photovoltaic support]

Can photovoltaic support steel pipe screw piles survive frost jacking?

To study the frost jacking performance of photovoltaic support steel pipe screw pile foundations in seasonally frozen soil areas at high latitudes and low altitudes and prevent excessive frost jacking displacement, this study determines the best geometric parameters of screw piles through in situ tests and simulation methods.

What are the different types of photovoltaic support foundations?

The common forms of photovoltaic support foundations include concrete independent foundations, concrete strip foundations, concrete cast-in-place piles, prestressed high-strength concrete (PHC piles), steel piles and steel pipe screw piles. The first three are cast-in situ piles, and the last three are precast piles.

What is a PHC (pre-stressed high-strength concrete) pile foundation?

The PHC (pre-stressed high-strength concrete) pile foundation, serving as an innovative supporting structure for solar power stations, is subjected to complex loading conditions in engineering scenarios.

How to measure the deformation and stress state of PHC piles?

However, due to the fact that the foundation part of PHC piles was buried in the soil, it was challenging to obtain the deformation and stress state through monitoring means. There was no direct test method available for measuring the deformation of short pile foundations beneath the ground.

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.

What is the Frost jacking of the photovoltaic pile?

Considering the thawing settlement of the pile body, within the 25-year service period of the photovoltaic power project, the frost jacking of the pile is approximately 144.68 mm. anti-frost jacking measures are recommended to reduce the impact of frost heaving.
