Experimental and numerical investigations on the mechanical

The study assessed the inclination of the column top, ground displacement, and torsion to analyze the stress and deformation characteristics of PHC pile foundations. The deformation of PHC

Experimental study on the anti-jacking-up performance of a screw pile

The soils in seasonal frozen regions freeze and thaw frequently, causing severe frost heave and thaw settlement problems, which bring challenges to piles of photovoltaic

STRUCTURAL INTEGRITY EVALUATION OF PILE FOUNDATIONS BY PILE

Pile foundations have been widely used to support heavy superstructures on soft soil. A pile foundation may be either prefabricated and driven into soil or constructed in situ. During or

Experimental study on the anti-jacking-up performance of a screw pile

Piles are a common type of foundation to support engineering structures in frozen ground, but they may suffer from heaving once sufficiently moist frost-susceptible soils freeze

Experimental study on the anti-jacking-up performance of a screw pile

6 FAQs about [Experimental record of photovoltaic support pile foundation]

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.

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.

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 inclination affect the deformation characteristics of PHC pile foundations?

The study assessed the inclination of the column top, ground displacement, and torsion to analyze the stress and deformation characteristics of PHC pile foundations. The deformation of PHC short pile foundations exhibited distinct phases. Torsional load reduced the column crack load by 30%.

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.

Can helical piles be used for ground-mounted solar PV systems?

For ground-mounted solar PV systems, two different pile foundation types were experimentally analysed for the pull-out test in clayey, sandy, and mixed ( c – ϕ) soils. Maximum uplift load at failure of various diameter and length were compared for plain piles with helical piles.
