Lateral Load Behavior of Full-Scale Pile Group in Clay

Modeling the lateral response of pile groups in cohesionless and cohesive soils

“…trailing row). This is also reported by Brown et al [5] and Rollins et al [20][21][22][23][24][25][26][27][28][29]. Same discussion obtained from predicted p-y curve of group 2 × 1 can be applied for both pile group 2 × 2 and 3 × 2.…”

“…For the same magnitude of lateral load of 450 kN, group interaction obtained showed an increase in lateral pile displacement. This conclusion was also supported by Brown et al [5], and Rollins et al [20][21][22][23][24][25][26][27][28][29]. It can be seen that the pile spacing less than 6D resulted in a large lateral deflection of a pile group under applied load due to group high group interaction effect.…”

“…450 kN) due to the effect of pile spacing is significant. The ultimate soil resistance of laterally loaded piles decreases significantly with increase in pile spacing [5,[20][21][22][23][24][25][26][27][28][29]. It can also be observed that, in the case of 2 × 2 pile group the pile in same row has same lateral capacity.…”

Laterally Loaded Single Pile Response Considering the Influence of Suction and Non-Linear Behaviour of Reinforced Concrete Sections

“…The errors are higher for lower values of the relative displacements (y/D) and lower load level (H measured /H max test ). This statement is referred to the cases reported in [31,42,45,54]. In [45,54] the piles were filled with grout, so the initial pile flexural rigidity could be affected by the steel/grout interaction.…”

“…This statement is referred to the cases reported in [31,42,45,54]. In [45,54] the piles were filled with grout, so the initial pile flexural rigidity could be affected by the steel/grout interaction. In [31,42] the measured load vs. horizontal displacement plots present for lower load levels an unusual trend compared to the other cases.…”
