Field Experimental Study of Lateral Load Capacity of Bored Pile in Soft Soil
The lateral bearing characteristic of pile is complex for the soil-pile interaction. The field static loading test is scarce. Based on the project of the DongtiaoxiBridge in Huzhou City, a field test was carried out in order to study lateral bearing capacity of pile. The soft soil (including back-filled soil), silt clay and muddy clay are distributed in the site area, and the depth of the clay is more than 40m. For testing the axial force of pile and the distribution of bending moment under lateral load, reinforcement meter was welded to the steel cage at different levels before the bored pile was constructed. The inclinometer casing was used to obtain the lateral displacement distribution of pile along the depth. The result shows that the lateral bearing capacity of pile is more than 1100 kN, and the displacement at loaded point is only 2.66 mm. The maximum bending moment of pile is about 4 m below the soil surface. The bending moment transfers to the deeper location with the increase of the horizontal load, and the bend deformation only occurs in the upper 1/6 of pile length. The ground coefficient decreases and the decrease extent is smaller as the lateral deformation increases.
