Experimental Study on Horizontal Bearing Characteristics of Screw Pile

The horizontal bearing capacity of the screw pile and monopile was analyzed by model tests. Results showed that the horizontal bearing capacity of the screw pile was significantly greater than that of the monopile under the same loading conditions. With the increase in horizontal loading speed, the ultimate horizontal bearing capacity of the two piles also increases, and the difference decreases gradually. Moreover, the influence of vertical loading on the horizontal bearing capacity of screw pile and monopile is studied at the horizontal loading speed of 2 mm s⁻¹. The findings indicate that vertical load evidently affects the horizontal bearing capacity of common piles, but slightly influences the horizontal bearing capacity of screw piles.
