Numerical analysis of the boundary effect in model tests for single pile under lateral load

Inertial and kinematic interactions of bridge‐pile group subjected to liquefaction induced lateral spreading: Large‐scale shaking table experiments

“…The shear box limits the soil displacement perpendicular to the shaking direction. In addition, when the soil box length is greater than 15 times the pile diameter, the influence of the lateral boundary on the pile response is insignificant 51 . The soil box used in this test was 3.2 m (32 times the pile diameter) along the shaking direction, which meets the soil box's length requirements.…”

It has been used successfully in the shaking table testing of liquefiable soil-pile group-structure systems.…”

Calculative Width of Pile Foundation on Slope Based on Particle Image Velocimetry (PIV)

“…e physical simulation was carried out in the threedimensional mechanical model system test bed, the dimension of which is 4 m × 2 m × 1.5 m. e boundary effect considered in this test is 5-9 times the diameter of the pile [16], and the size of the three-dimensional model is 1.5 m × 1.1 m × 1.5 m. Plane sketch of the model is shown in Figure 1, profile under 15°slope is shown in Figure 2, and scene diagram of the indoor test is shown in Figure 3.…”

“…e numerical model takes into account the working conditions of 0°, 15°, 30°, and 45°slope under the same soil and pile parameters. Tetrahedron was used to mesh in order to improve the running speed and reduce the boundary effect [16]. e dimension of the numerical model is 200 m × 100 m × 80 m. According to the full-scale test, the size of the model pile is 1 m × 1 m × 10 m and the length of the pile body exposed is 1 m. e generalized numerical model for 45°slope is shown in Figure 19.…”
